How to generate pdf files _with_ utf-8 multibyte characters using Zend Framework

Question

Hello, I've got a "little" problem with Zend Framework Zend_Pdf class. Multibyte characters are stripped from generated pdf files. E.g. when I write aąbcčdeę it becomes abcd with lithuanian letters stripped.

I'm not sure if it's particularly Zend_Pdf problem or php in general.

Source text is encoded in utf-8, as well as the php source file which does the job.

Thank you in advance for your help ;)

P.S. I run Zend Framework v. 1.6 and I use FONT_TIMES_BOLD font. FONT_TIMES_ROMAN does work

Answer 1

I believe Zend_Pdf got UTF-8 support in 1.5 - What version of Zend Framework are you running?

Also - what font are you trying to render with? Have you tried alternate fonts?

Answer 2

ZF v. 1.6, TIMES_BOLD (as I understand thats the only way to make text bold?)

Answer 3

Have you made sure that you are setting the character encoding as this example from the manual?

// Draw the string on the page
$pdfPage->drawText($unicodeString, 72, 720, 'UTF-8');

If you're stuck into having to use a bold font, maybe try one of the other bold fonts?

Zend_Pdf_Font::FONT_COURIER_BOLD
Zend_Pdf_Font::FONT_TIMES_BOLD
Zend_Pdf_Font::FONT_HELVETICA_BOLD

Answer 4

Zend_Pdf supports UTF-8 in version 1.5 of Zend Framework. However, the standard PDF fonts support only the Latin1 character set. This means you can't use Zend_Pdf_Font::FONT_TIMES_BOLD or any other "built-in" font. To use special characters you must load another TTF font that includes characters from other character sets.

I use Mac OS X, so I tried the following code and it produces a PDF document with the correct characters.

$pdfDoc = new Zend_Pdf();
$pdfPage = $pdfDoc->newPage(Zend_Pdf_Page::SIZE_LETTER);

// load TTF font from Mac system library
$font = Zend_Pdf_Font::fontWithPath('/Library/Fonts/Times New Roman Bold.ttf');
$pdfPage->setFont($font, 36);

$unicodeString = 'aąbcčdeę';
$pdfPage->drawText($unicodeString, 72, 720, 'UTF-8');

$pdfDoc->pages[] = $pdfPage;
$pdfDoc->save('utf8.pdf');

Hi!

The utf-8 charakters work here... but the newlines (\r \n) are replaced with an little block symbol, instead of an enter. How to fix this? (I'm using the gorilla-pdf extension with tables).
