I have since sending my original message moved my draft proposal to U+E9D0, as
many of the blocks in between surprisingly have characters in my system fonts
I also made up two fonts (one TrueType, sized to work with Luxi Mono; the
other a bitmap, matching the KDE 3 "Console" font) for my own personal testing
of these proposals.

Correct me if my understand is wrong, but I believe them to be combining
because they can and should "attach" to some degree to the unit character
preceding (in the case of division) or following (in the case of
multiplication) the divisor/multiplier. It is for this font-encoding purpose
that I created two sets which can attach in their specific direction.

Aren't superscript/subscript letters compatibility-only as well? Other than
the possibly combining needs, I hope an exception (if needed) could be
considered so as to not require rich text simply to type up a unit.

I only have Nystrom's book as my guide on this, and it does not specify how
exactly the higher-order multipliers and divisors are supposed to be written
abbreviated. It is possible they were not meant to be at all, but this theory
would create problems in present day when such numbers are more commonplace.
How might I phrase it such that it is clear the extra space is only for a
later discovery of Nystrom's extending of Tonal?
Thanks for all the other comments as well,
