An important part of Ricardo Niemietz's hex digit proposal
(http://std.dkuug.dk/jtc1/sc2/wg2/docs/n2677) is to have columns of
hexadecimal numbers line up properly as columns of decimal numbers do.
This could be achieved using a font with a set of glyph variants for A-F
with a hexadecimal property. Such a glyph variant table could be added
to, for example, an OpenType font. Then a display engine that encounters
a text run with the hexadecimal property could request the hexadecimal
glyph variants. This mechanism is similar to requesting old-style
numerals when a document so specifies. Seems like a good idea.
As Mark and Ken have pointed out numerous times, changing other aspects
of hex digits is fraught with compatibility problems.
