 BUGS and Outstanding Issues 
 
-
-Using SDL::TTFont::width function with UTF-8 encoded strings returns 
-the width of the characters that make up the UTF-8 format and not what 
-they represent.  The function for this appears to exist in SDL.xs: 
-
-AV* TTFSizeUTF8 ( font, text )
-
-However, this function crashes immediately when called with a valid 
-font and [utf-8 encoded] string.
