Description pjz 2018-09-03 07:21:42 UTC 
I propose a patch with added proper UTF-16 and characters outside the BMP support, which extends the fix to the bug #3762. The code can be found at <https://github.com/acmepjz/SDL_ttf/tree/utf16-fix>.

* Change the UCS-2 code to UTF-16 code, which allows characters outside the BMP range

* Change various public functions (TTF_GlyphIsProvided, TTF_GlyphMetrics, TTF_RenderGlyph_***, etc.) to accept Uint32 for character instead of Uint16

* Also added a UTF-32 to UTF-8 conversion routine (which is only used in TTF_RenderGlyph_***)
