Q:
How do I get the glyph for a Unicode character?
A:
The proper way to get the glyph for a Unicode character, is by using the character code (charcode) used in the PDF to display the glyph. A font can have multiple glyphs representing any particular Unicode character.
So the proper way is with the char code
PathData path_data = font.GetGlyphPath(char_code);
UString unicode = font.MapToUnicode(char_code);
While the mapping from char_code to glyph is 1:1, the mapping of char_code to unicode can be 1:many (for instance ligatures, such as “ffi”)
And as mentioned above, a glyph can have multiple charcodes mapping to itself, and any Unicode character could have multiple charcodes mapping to it.
If you really need to get a glyph for a unicode character, the following will work.
unsigned int max_char_code = font.IsSimpl() ? 0xFF : 0xFFFF; UString uni; for(unsigned int cc = 0; cc < max_char_code; ++cc) { uni = font.MapToUnicode(cc); if(!uni.Empty() && uni.GetLength() == 1) // uni could contain multiple unicode characters { if(uni.GetAt(0) == unicode_target) { // you now have a matching charcode for that unicode character. // you could either break now, or continue searching for additional charcodes. // There may be more than one glyph for this unicode, in which case there would // would be at least that many charcodes mapping to this unicode. } } } // now using matched charcode(s), you can call font.GetGlyphPath()
