UserFontFace.setUnicodeToGlyphFunc

Sets the unicode-to-glyph conversion function of a user-font. See cairo_user_scaled_font_unicode_to_glyph_func_t for details of how the callback works. The font-face should not be immutable or a CAIRO_STATUS_USER_FONT_IMMUTABLE error will occur. A user font-face is immutable as soon as a scaled-font is created from it. Since 1.8
