> The method o.a.f.fonts.Font.getKernValue expects two Unicode code points and
> returns the amount of kerning between the two corresponding glyphs. However,
> the implementation for Type 1 fonts interprets the two integers as character
> codes in the font's internal encoding (see o.a.f.fonts.type1.AFMFile.java).
> Those usually have nothing to do with Unicode code points.
> Moreover, trying to get kerning between two characters is inherently wrong:
> kerning applies to glyphs and not characters. A font may have several glyph
> variants for a same character, and kerning is likely to be different for each
> variant.
