in math-vfu, patch:
--~ main.characters[unicode] = { horiz_variants = t }
main.characters[unicode].horiz_variants = t
and
[0x02190] = 0x20, -- leftarrow
[0x02192] = 0x21, -- rightarrow
--~ [0xFE190] = 0x20, -- leftarrow
--~ [0xFE192] = 0x21, -- rightarrow
and remake the format
luatex has native support for extensible arrows and since lm lacks them
we need to construct them
