i’m quite excited to find out that most of what i want is already in mkiv!
regarding the problems you mentioned:
1. the super/subscripts could be interpreted like x²³₄₅ → x^{23}_{45} or
couldn’t they? if you want to do more complex stuff (more than one level of
super/subscripting), the super/subscripts are only for the last level:
x^{2³}_{4₅} → x^{2^3}_{4_5}
i can look into it ... but it's up to you to provide some test files
first so that we can determine to what extend we go
2. maybe the use of unicode fractions and sfrac as a fallback would be
nice for inline math: 4 ⁄ 5 → ⅘, 8 ⁄ 9 → \sfrac89. for display it would
be {4 \over 5} and {8 \over 9} (maybe i don’t get your point: isn’t \over
context’s way of doing fractions?)
well, we could also support display but we might pose some restrictions
2a / b
vs
2 a/b
3. you mean “\√” yields “√”? of course! it’s like a “” or a “\”, then.
indeed, but introducing more commands like \√ might not be the way to go
as we try to get rid of etc being special (i've even be thinking os
some special unicode char, maybe a private pair, for $ $ replacement
4. you mean
thishttp://www.unicode.org/notes/tn28/UTN28-PlainTextMath-v2.pdf.
nice thing, worth more than one look! maybe really the direction of the
future?
indeed and as with cambria it's microsoft currently leading the way ..
in my opinion the tex math community lost the lead long ago so we have
to follow now (stix is a good example ... we could probably easily test
those fonts in mkiv but no one cares)

[dev-context] unicode-math
hi,
context in combination with luatex is quite the way to go for me, but i have
one thing that i would love to see inside context:
unicode-mathhttp://github.com/wspr/unicode-math!
the guys there are making a good job of mapping tons of unicode sequences to
latex commands, so we should really profit from this project.
is it possible to integrate it into context or to create a package for this
purpose?
i would love to write $y = x² ± 2µ ⇒ y ≠ √{α ⁄ 5}$, while still being able
to write $y = x^2 \pm 2\mu \Rightarrow y \neq \frac{α \over 5}$ or any
combination of the two.
i would too love to participate in a project making this possible, but i
don’t know how to start coding (i could only write a preprocessor in python
doing this, but that would be rather a workaround than the true thing.)
thanks,
phil
PS: the ⁄ i used is a „fraction slash“, not a simple solidus, which of
course would still be rendered as solidus.

Most of the tedious work is already there: your test above actually
renders something, because the unicode math characters in context mkiv
are all (or at least almost all) defined to render themselves as math
glyphs.
What is missing is the mapping of the special constructs like
√{a⁄b} - \frac{a}{b}
so if you can extract a list of those from the unicode-math project,
it would be pretty straightforward to add support for this kind of
input, I think.
Best wishes,
Taco
