FPDF utf-8 encoding (HOW-TO)

Question

Does anybody know how to set the encoding in FPDF package to UTF-8? Or at least to ISO-8859-7 (Greek) that supports Greek characters?

Basically I want to create a PDF file containing Greek characters.

Any suggestions would help. George

Answer 1

Don't use UTF-8 encoding. Standard FPDF fonts use ISO-8859-1 or Windows-1252. It is possible to perform a conversion to ISO-8859-1 with utf8_decode(): $str = utf8_decode($str); But some characters such as Euro won't be translated correctly. If the iconv extension is available, the right way to do it is the following: $str = iconv('UTF-8', 'windows-1252', $str);

Answer 2

You have two options to achieve real UTF-8 support:

1. Use official UTF-8 Version tFPDF

There also is a official UTF-8 Version of FPDF called tFPDF http://www.fpdf.org/en/script/script92.php

You can easyly switch from the original FPDF, just make sure you also use a unicode Font as shown in the example in the above link or my code:

<?php

//this is a UTF-8 file, we won't need any encode/decode/iconv workarounds

//define the path to the .ttf files you want to use
define('FPDF_FONTPATH',"../fonts/");
require('tfpdf.php');
    
$pdf = new tFPDF();
$pdf->AddPage();
    
// Add Unicode fonts (.ttf files)
$fontName = 'Helvetica';
$pdf->AddFont($fontName,'','HelveticaNeue LightCond.ttf',true);
$pdf->AddFont($fontName,'B','HelveticaNeue MediumCond.ttf',true);

//now use the Unicode font in bold
$pdf->SetFont($fontName,'B',12);

//anything else is identical to the old FPDF, just use Write(),Cell(),MultiCell()... 
//without any encoding trouble
$pdf->Cell(100,20, "Some UTF-8 String");

//...
?>

I think its much more elegant to use this instead of spaming utf8_decode() everywhere and the ability to use .ttf files directly in AddFont() is an upside too.

Any other answer here is just a way to avoid or work around the problem, and avoiding UTF-8 is no real option for an up to date project.

2. Use an alternative Project like mPDF or TCPDF

There are also alternatives that I would prefer like mPDF or TCPDF (and others) wich base on FPDF but offer advanced functions, have UTF-8 Support, can interpret HTML Code (limited of course as there is no direct way to convert HTML to PDF) and are under active developement. Most of the FPDF code can be used directly in those librarys, so its pretty easy to migrate the code.

Answer 3

there is a really simple solution for this problem.

In the file fpdf.php go to the line that says:

if($txt!=='')
{

It is line 648 in my version of fpdf. Insert the following line of code:

$txt = iconv('utf-8', 'cp1252', $txt);

(above the line of code)

if($align=='R')

This works for all German special characters and should also work for Greek special characters. Otherwise simply replace cp1252 with the respective alphabet you require. You can see all supported characters here: http://en.wikipedia.org/wiki/Windows-1252

I saw the solution here: http://fudforum.org/forum/index.php?t=msg&goto=167345 Please use my example code above, as the original author forgot to insert a dash between utf and 8.

Hope the above was helpful.

You need to generate a font first. You must use the MakeFont utility included within the FPDF package. I used on Linux this a bit extended script from the demo:

<?php
// Generation of font definition file for tutorial 7
require('../makefont/makefont.php');

$dir = opendir('/usr/share/fonts/truetype/ttf-dejavu/');
while (($relativeName = readdir($dir)) !== false) {
    if ($relativeName == '..' || $relativeName == '.')
        continue;
    MakeFont("/usr/share/fonts/truetype/ttf-dejavu/$relativeName",'ISO-8859-2');
}
?>

Then I copied generated files to the font directory of my web and used this:

$pdf->Cell(80,70, iconv('UTF-8', 'ISO-8859-2', 'Buňka jedna'),1);

(I was working on a table.) That worked for my language (Buňka jedna is czech for Cell one). Czech language belongs to central european languages, also ISO-8859-2. Regrettably the user of FPDF is forced to lost advantages of UTF-8 encoding. You cannot get this in your PDF:

Městečko Fruens Bøge

Danish letter ø becomes ř in ISO-8859-2.

Suggestion of solution: You need to get a Greek font, generate the font using proper encoding (ISO-8859-7) and use iconv with the same target encoding as the one the font has been generated with.

Answer 5

How do I create PDF's in FPDF that support Chinese, Japanese, Russian, etc.?

(snapshots of code in use below)

I'd like to provide: a summary of the problem, the solution, a github project with the working code, and an online example with the expected, resultant PDF.

The Problem :

1. As stated by Tarsis, swap FPDF to TFPDF.

2. You actually need a font that supports the UTF-8 characters you are using.

   I.E., merely using Helvetica and trying to display Japanese will not work. If you use Font Forge, or some other font tool, you can scroll to the Chinese characters of the font, and see that they are blank.

   Google has a font (Noto font) that contains all languages, and it is 20mb, which is usually several factors the size of your text. So, you can see why many fonts simply won't cover every single language.

The Solution :

I'm using rounded-mgenplus-20140828.ttf and ZCOOL_QingKe_HuangYou.ttf font packs for Japanese and Chinese, which are open source and can be found in many open source projects. In tFPDF itself, or a new inheriting class of it, like class HTMLtoPDF extends tFPDF {...}, you'll do this...

$this->AddFont('japanese', '', 'rounded-mgenplus-20140828.ttf', true);
$this->SetFont('japanese', '', 14);
$this->Write(14, '日本語');

Should be nothing more to it!

Answer 6

This answer didn't work for me, I needed to run html decode on the string also. See

iconv('UTF-8', 'windows-1252', html_entity_decode($str));

Props go to emfi from html_entity_decode in FPDF(using tFPDF extention)

Answer 7

just edit the function cell in the fpdf.php file, look for the line that looks like this

function cell ($w, $h = 0, $txt = '', $border = 0, $ln = 0, $align = '', $fill = false, $link = '')
{ 

after finding the line

write after the {,

$txt = utf8_decode($txt);

save the file and ready, the accents and the utf8 encoding will be working :)

Answer 8

There is an extension of FPDF called mPDF that allows Unicode fonts.

http://www.mpdf1.com/mpdf/index.php

Answer 9

None of the above solutions are going to work.

Try this:

function filter_html($value){
    $value = mb_convert_encoding($value, 'ISO-8859-1', 'UTF-8');
    return $value;
}

Answer 10

You can make a class to extend FPDF and add this:

class utfFPDF extends FPDF {

function Cell($w, $h=0, $txt="", $border=0, $ln=0, $align='', $fill=false, $link='')
{
    if (!empty($txt)){
        if (mb_detect_encoding($txt, 'UTF-8', false)){
            $txt = iconv('UTF-8', 'ISO-8859-5', $txt);

        }
    }
    parent::Cell($w, $h, $txt, $border, $ln, $align, $fill, $link);

} 

}

Answer 11

I wanted to answer this for anyone who hasn't switched over to TFPDF for whatever reason (framework integration, etc.)

Go to: http://www.fpdf.org/makefont/index.php

Use a .ttf compatible font for the language you want to use. Make sure to choose the encoding number that is correct for your language. Download the files and paste them in your current FPDF font directory.

Use this to activate the new font: $pdf->AddFont($font_name,'','Your_Font_Here.php');

Then you can use $pdf->SetFont normally.

On the font itself, use iconv to convert to UTF-8. So if for example you're using Hebrew, you would do iconv('UTF-8', 'windows-1255', $first_name).

Substitute the windows encoding number for your language encoding.

For right to left, a quick fix is doing something like strrev(iconv('UTF-8', 'windows-1255', $first_name)).

Answer 12

You can apply this function on your text :

 $yourtext = iconv('UTF-8', 'windows-1252', $yourtext);

Thanks

Answer 13

Like many said here:

$yourtext = iconv('UTF-8', 'windows-1252', $yourtext);

BUT! with an '//Ignore' after the windows-1252 or in my case CP1252, like this:

iconv("UTF-8", "CP1252//IGNORE", $row['project_name'])

This one worked for me, I hope it works for you!

Answer 14

Not sure if it will do for Greek, but I had the same issue for Brazilian Portuguese characters and my solution was to use html entities. I had basically two cases:

1. String may contain UTF-8 characters.

For these, I first encoded it to html entities with htmlentities() and then decoded them to iso-8859-1. Example:

$s = html_entity_decode(htmlentities($my_variable_text), ENT_COMPAT | ENT_HTML401, 'iso-8859-1');

2. Fixed string with html entities:

For these, I just left htmlentities() call out. Example:

$s = html_entity_decode("Treasurer/Trésorier", ENT_COMPAT | ENT_HTML401, 'iso-8859-1');

Then I passed $s to FPDF, like in this example:

$pdf->Cell(100, 20, $s, 0, 0, 'L');

Note: ENT_COMPAT | ENT_HTML401 is the standard value for parameter #2, as in http://php.net/manual/en/function.html-entity-decode.php

Hope that helps.

Answer 15

For offsprings.

How I managed to add russian language to fpdf on my Linux machine:

1) Go to http://www.fpdf.org/makefont/ and convert your ttf font(for example AerialRegular.ttf) into 2 files using ISO-8859-5 encoding: AerialRegular.php and AerialRegular.z

2) Put these 2 files into fpdf/font directory

3) Use it in your code:

$pdf = new \FPDI();
    $pdf->AddFont('ArialMT','','ArialRegular.php');
    $pdf->AddPage();
    $tplIdx = $pdf->importPage(1);
    $pdf->useTemplate($tplIdx, 0, 0, 211, 297); //width and height in mms
    $pdf->SetFont('ArialMT','',35);
    $pdf->SetTextColor(255,0,0);
    $fullName = iconv('UTF-8', 'ISO-8859-5', 'Алексей');
    $pdf->SetXY(60, 54);
    $pdf->Write(0, $fullName);

Answer 16

Instead of this iconv solution:

$str = iconv('UTF-8', 'windows-1252', $str);

You could use the following:

$str = mb_convert_encoding($str, "UTF-8", "Windows-1252");

See: How to convert Windows-1252 characters to values in php?

Answer 17

There's an extention to FPDF called UFDPF http://acko.net/blog/ufpdf-unicode-utf-8-extension-for-fpdf/

But, imho, it's better to use mpdf if you're it's possible for you to change class.

Answer 18

I use FPDF for ASP, and the iconv function is not available. It seems strange, by I solved the UTF-8 problem by adding a fake image (an 1x1px jpeg) to the pdf, just after the AddPage() function:

pdf.Image "images/fpdf.jpg",0,0,1

In this way, accented characters are correctly added to my pdf, don't ask me why but it works.

Answer 19

I know that this question is old but I think my answer would help those who haven't found solution in other answers. So, my problem was that I couldn't display croatian characters in my PDF. Firstly, I used FPDF but, I think, it does not support Unicode. Finally, what solved my problem is tFPDF which is the version of FPDF that supports Unicode. This is the example that worked for me:

require('tFPDF/tfpdf.php');
$pdf = new tFPDF();
$pdf->AddPage();
$pdf->AddFont('DejaVu','','DejaVuSansCondensed.ttf',true);
$pdf->AddFont('DejaVu', 'B', 'DejaVuSansCondensed-Bold.ttf', true);

$pdf->SetFont('DejaVu','',14);

$txt = 'čćžšđČĆŽŠĐ';
$pdf->Write(8,$txt);

$pdf->Output();

Answer 20

For me none of the answered worked. I just wanted to print some symbols. So this was my code which worked.

$pdf->AddFont('Symbol','','symbol.php');
$pdf->SetFont('Symbol','',35);
$pdf->Write(10,chr(229));
