have you overlooked the smiley? what's the saying: a million flies
can't err?  all i was commenting on here is that it isn't as bad as in
the days of typewriter and i think we can agree on that.

because bold and slanted do not normally have to do with
encodings. just as we don't have bold and normal weight chars in T1
but we use two T1 encoded fonts for that.

if you would like a bold script then you would use a second MSP
encoded font and your done. granted you then waste some slots because
also the other glyphs of that font are bold and you might not want all
of them but then one can have only one alphabet per font if the glyphs
are to be accessible directly so putting more than one into a font is
not a good idea for that reason

so the proposal already allows for having bold/bold/slanted versions
and there is no need to *add* them to the encoding proposal

but they are in the encoding proposal: MS1 has 64 glyphs bbb glyphs (p.34)
and MS2 a fraktur alphabet

if you read carefully you find MS1 (point 14 page 35) Alan's arrow
construction set as a possible suggestion for inclusion

but it has --- during the discussion on the math font list that
resulted in the proposal --- but it is conveniently be solved by
additional fonts in the same encoding

(and yes kerning is a problem but that was looked at as well and
within TeX you are limited to kern only within one font so there is
unfortunately no way to get *all* kerns you ideally want. for this we
have to wait for omega)
