That's one of the "other drawbacks" I meant. They're not "for" that.
My MathText tool at http://users.adelphia.net/~dewell/mathtext.html,
which blatantly abuses Unicode by converting plain text to math symbols
and back, was intended as an April Fool's joke, although it is fully
functional and has reportedly been used for font testing.
This brings up the topic of "Unicode abuse" in general. Conformance to
the Unicode Standard (see DUTR #33, of which Asmus is a co-author)
generally refers to support for and adherence to the "letter of the
law," things like implementing normalization and casing correctly. It's
not quite so easy to quantify adherence to the "spirit of the law," in
terms of things like abusing math characters and compatibility
characters, or using directional overrides where they don't harm
anything and aren't invalid, but also aren't necessary or appropriate.
This almost falls into the same category as spoofing, which is being
addressed in a different UTR, but seems different somehow.
Clearly it's a bad thing to use characters for inappropriate purposes,
but there is a long history of people doing this with ASCII, and I've
even seen math symbols used 𝑓𝑜𝑟 𝑒𝑚𝑝ℎ𝑎𝑠𝑖𝑠 on this list.
How does one go about measuring the type of "conformance" that relates
to using Unicode for the "right" purposes versus the "wrong" purposes?
