SingleByteFont, MultiByteFont: A font is not really single or multibyte. Rather the name SingleByteFont indicates that the font does not contain more than 256 glyphs; the implementation is optimized for this. In MultiByteFont (actually CIDFont Type2) the implementation is optimized for fonts with an unknown number of glyphs.
