Bug 2486

Summary: Asian languague support for TTF_RenderUTF8_Blended_Wrapped() in SDL_ttf-2.0.12
Product: SDL_ttf Reporter: George Wu <micstu>
Component: miscAssignee: Sam Lantinga <slouken>
Status: RESOLVED DUPLICATE QA Contact: Sam Lantinga <slouken>

Description George Wu 2014-04-09 13:39:04 UTC 
Created attachment 1611 [details]
Modified source code of SDL_ttf.c.

SDL_ttf didn't quite show hospitability to Asian languages using UTF-8 and UNICODE . When using TTF_RenderUTF8_Blended_Wrapped() function (which the other to *_Blended_Wrapped() functions finally calls), it generates overlapped characters and wrong line wrapping. This patch is intended to fix these issues.
The change I made begins from line 1849 and ends from line 2277, see attachment. Please ignore changes elsewhere. It does work on my system, but robustness is not assured. I would be glad if someone tests it on an OS other than Windows.

The modified file is based on the last release and also contains an unused TTF_SetFontSize() from bug 2487.

A related bug is 2492 (it links here).
