freetypy.Face.get_char_index

Face.get_char_index()

Get the glyph index of a given char code.

This function uses a charmap object to do the mapping.

Parameters:charcode (int) – The char code. Returns:glyph_index – The glyph index. 0 means ‘undefined char code’. Return type:int

Notes

If you use FreeType to manipulate the contents of font files directly, be aware that the glyph index returned by this function doesn’t always correspond to the internal indices used within the file. This is done to ensure that value 0 always corresponds to the ‘missing glyph’. If the first glyph is not named ‘.notdef’, then for Type 1 and Type 42 fonts, ‘.notdef’ will be moved into the glyph ID 0 position, and whatever was there will be moved to the position ‘.notdef’ had. For Type 1 fonts, if there is no ‘.notdef’ glyph at all, then one will be created at index 0 and whatever was there will be moved to the last index – Type 42 fonts are considered invalid under this condition.
