Presta 1.5 can't display Chinese characters in pdf documents.

[Czarekplpl]

Hello.

My Presta 1,5 display small squares instead Chinese characters.

In the back office Chinese fonts are displayed OK.

Is there anybody having the same problem?

You have no Chinese fonts installed.

It could be.

Can you tell me how to do it???

Search the forum. I think someone had the same problem.

I already searched the newest topic is from 2011 Presta 1.2

I think I should implement 'kozminproregular';

But I do not know what encoding should I use?

Hello.

I found solution myself. For Presta 1,6 and 1,5

Go to Classes>Pdf>PdfGenerator.php and find this place:

class PDFGeneratorCore extends TCPDF
{
	const DEFAULT_FONT = 'helvetica';

	public $header;
	public $footer;
	public $content;
	public $font;

	public $font_by_lang = array(
		'ja' => 'cid0jp', 
		'bg' => 'freeserif', 
		'ru' => 'freeserif', 
		'uk' => 'freeserif', 
		'mk' => 'freeserif', 
		'el' => 'freeserif', 
		'en' => 'dejavusans',		
		'vn' => 'dejavusans', 
		'pl' => 'dejavusans',
		'ar' => 'dejavusans',
		'fa' => 'dejavusans',
		'ur' => 'dejavusans',
		'az' => 'dejavusans',
		'ca' => 'dejavusans',
		'gl' => 'dejavusans',
		'hr' => 'dejavusans',
		'sr' => 'dejavusans',
		'si' => 'dejavusans',
		'cs' => 'dejavusans',
		'sk' => 'dejavusans',
		'ka' => 'dejavusans',
		'he' => 'dejavusans',
		'lo' => 'dejavusans',
		'lv' => 'dejavusans',
		'tr' => 'dejavusans',
		'ko' => 'cid0kr',
		'zh' => 'cid0cs',
		'tw' => 'cid0cs',
		'th' => 'freeserif'
		);


	public function __construct($use_cache = false)
	{
		parent::__construct('P', 'mm', 'A4', true, 'UTF-8', $use_cache, false);
		$this->setRTL(Context::getContext()->language->is_rtl);
	}

Than change it like this:

class PDFGeneratorCore extends TCPDF
{
	const DEFAULT_FONT = 'cid0cs';

	public $header;
	public $footer;
	public $content;
	public $font;

	public $font_by_lang = array(
		
		'zh' => 'cid0cs',
		
		);


	public function __construct($use_cache = false)
	{
		parent::__construct('P', 'mm', 'A4', true, 'gb2312', $use_cache, false);
		$this->setRTL(Context::getContext()->language->is_rtl);
	}

Generally:

Change helvetica font.

Delete useless languages, leave only 'zh' => 'cid0cs',

Change encoding.

Than on English language documents  Chinese characters are displayed correctly (address, names, etc....)

Probably it works for other languages too.
