Hi Thanks all for your inputs I debugged the issue and the problem was found to be in the function GetFontFromCollection. For fonts like MS Gothic we are not getting inside the following condition if(platformID == 0 && languageID == 0)
It seems that in name table such fonts don't have an entry with platform ID=0(Unicode platform). I observed that mainly this part of code is used extract information like fontfamily, fontstyle etc and later to verify if we have the correct font. (I guess the same information can be obtained from platform ID 3 encoding ID 1 or something else) (are such verification done for ttf fonts?) So I removed the verification part , ie if(isMatchingFont) was set to if(true), so the buffer will be created for all fonts . Now all ttc fonts are working fine. I hope proper fix will be released in the next release Thanks and regards Ali -----Original Message----- From: dennis [mailto:dennis.v...@dots.de] Sent: Monday, February 01, 2016 1:08 PM To: podofo-users@lists.sourceforge.net Subject: Re: [Podofo-users] TTC Font Support Hi, (guy who implemented ttc support here). The problem is, the std::equal_range function call in pdf fontcache. (or better the constructor of TFontCacheElement) Meiro for example has a japanese name, thus the pdfstring will be converted into unicode (which is horribly buggy in podofo... with endless loops and such). Look at the CreateFontObject function in PdfFontCache. In there a TFontCacheElement is created. In the GetFont there is an std::equal_range call which uses a constructor of TFontCacheElement (here is the first buggy part). Just create the element beforehand like in CreateFontObject and then do the equal range call with the element (you "skip" the constructor which is buggy for unicode strings). This should fix your problem. If it doesnt you need to wait like 2 weeks xD. I have a patch but its not ready yet... Second buggy part (and that was my mistake...) is in GetFontFromCollection function in pdfFontCache. This needs some more rework. Which is kinda too complicated to describe in an email (patch is in the working dont worry ;D ) The problem is, that we first check the language id against the systemLCID or we check against english. This tends to give problems on systems with languagePacks installed which have a different "character" set then their native installation. (e.g. english system -> Japanese language pack, russian system -> german languagePack etc).
