Aren't you just being bitten by history? PDF derives from PostScript,
which is not a language for representing plain text with typesetting
information, but a language for type(and-graphic-)setting tout court.
There's a lot of history of fonts using arbitrary codepoints; the idea
that the underlying strings giving rise to the displayed graphics
should also be a good plain text representation of the information is
relatively novel.
