I have this problem exporting statistics in PDF file — only the question marks instead cyrillic symbols in the top side of PDF statistics files.
I include the follow string in config.php :
$chartfontfile='arialn.ttf';
$pdfdefaultfont='arialunicid0';
but it only fixes the font of diagrams and changes the font of the string under the top.
How to fix the font at the top of the PDF page?
If I need to change the default font (for top side of PDF) to utf8 cyrillic font, how may I do that?
Or it's a bug?
