Code2000 does not have hinting instructions; that's the font-wide strategy.

Do you have an example of either? Is it possible that any improper
alignment or disproportionate glyphs in your display are being caused
by something other than the font?

Trying to fix something which isn't broken is generally a bad plan. I
wonder if the bizarre behavior you're reporting might have been caused
by some third party "fixing" something in the font.

In a pan-Unicode font, the base of the CJK ideographs wouldn't be
expected to match the baseline of alphabetic scripts. Likewise, the
base of the stems used in Indic scripts shouldn't be expected to match
the baseline of alphabetic scripts as Indic scripts don't use
baselines. Rather, the glyphs in such a font might be designed so
that, even with reasonable above and below marks/diacritics, there
would be no excessive line gaps generated for the other scripts
covered in the font.

A font which made, for example, Tibetan base letters the same size as
Latin letters would work just fine... as long as you don't mind that
runs of Latin text displayed with the font would appear to have two or
three line feeds inserted between each line.
