    43 This is a Unicode private use area codepoint, which is reserved in the Symbian 

    44 OS to represent characters for which a glyph does not exist in a font (either 

    45 a bitmap or scalable font). If a glyph exists in a font with this character 

    46 code, it will be used for nonexistent characters, otherwise, the rasterizer's 

    47 default replacement character glyph will be used. For example, TrueType fonts 

    48 return glyph index 0 for nonexistent characters, and that is usually mapped 

    49 to an empty rectangle.
