CJK source code comment
type: item
description: I just installed TheIDE for linux (sabayon). I tried to insert some japanese comment to UWord source code. But nothing happened (no character shown). I also tried to enter japanese character at UWord, i got box character instead. One box character per IME session, i input many characters but only 1 box character shown. Does this feature already supported? Which source code part should i play with? Thanks

Thanks I guess, for the comment, make sure you have utf-8 encoding for the file first... Then the problem is fonts. AFAIK, "predefined" linux fonts do not contain CJK glyphs. In fact, they do not usually contain even anything else than ISO8859-1, but U++ goes over this limitation somewhat by synthetising characters in unicode range 256-512... Frankly, I am not 100% sure what to do with it. I guess we will need to pull CJK from other fonts than those predefined I guess (but at what priority?). BTW, speaking about it, what is the notion of font for CJK? I have noticed that for the limited number of fonts that support CJK on Win32, all glyps look basically the same, just the density is somewhat altered... (if this is the case, I could probably just use some "default CJK" font for missing glyphs or something like that..). Mirek

description: I have set to UTF-8 but still no luck. Thanks for mentioning the Win32. I think i saw this problem again at current UWord for XP. Another test with KDE 4.0.2, previously i tested against KDE 3.5.7. Now i can see box character inside TheIDE if i write something. Hope this help.

I tried to enumerate all fonts, and print japanese text using those fonts. Some of the font which able to print japanese are "kochi mincho" and "kochi gothic". Is there any algorithm to select this font automatically if we use Draw::DrawText function? Another one, which part of UPP codes do characters synthetising? Thanks

Don't have any experience with font world. Through google i got some links: http://en.wikipedia.org/wiki/Kochi_font http://ubuntuforums.org/archive/index.php/t-206280.html http://www.geocities.jp/ep3797/japanese_fonts.html

description: Having the same problem using U++ with Linux. My default charset and all my files are UTF-8, when I make a string and put some unicode characteres in there like: ♩♪♫♬♭♮♯ They show up as boxes, but they do work for the end-goal. In my case this is console output. Thus the problem lies with the rendering. Therefor I first tried different fonts in the environment settings, but no luck there. (these fonts do have success when using other programs like gnome text-editor). Then I tried an ide version compiled with NOGTK, but it has the same problem. Since it just the 'viewing' that is broken it might be low priority, but if you can take a look or direct me to the files I should look into; I'd be glad to help.

Draw/DrawTextXft.cpp Anyway, I think that the real cause is really missing glyphs in fonts and the fact that U++ does not look for missing glyphs in other fonts. That is a little bit more complex to fix... Mirek
