Replacement character code.

This is a Unicode private use area codepoint, which is reserved in the Symbian 
OS to represent characters for which a glyph does not exist in a font (either 
a bitmap or scalable font). If a glyph exists in a font with this character 
code, it will be used for nonexistent characters, otherwise, the rasterizer's 
default replacement character glyph will be used. For example, TrueType fonts 
return glyph index 0 for nonexistent characters, and that is usually mapped 
to an empty rectangle.
