Positive:

  FT_EXPORT( FT_UInt )
  FT_Get_Char_Index( FT_Face   face,
                     FT_ULong  charcode );

So, if you pass a small negative value to unsigned long charcode, you
will get a problem, that means a really big number.

I don't know what is best practice in C, declare text unsigned char * or
tell the compiler chars are unsigned or insert a type cast.

Hope that helps,

Christian
