apart from this IMHO very useful change (mapping to \int), maybe we should
create a unicode-math module which replaces some commands with symbols. i
find myself always using this for chemical and mathematical documents:
\catcode`→=\active
\def→{\xrightarrow}
\catcode`↔=\active
\def↔{\xleftrightarrow}
\catcode`√=\active
\def√{\sqrt}
Have a look at char-def.lua. All the symbol mappings are defined there.
Please feel free to complete the table (it is a boring and time consuming
process, and I have only managed to cover about half of the table).
Regarding your mappings, IIRC -> etc are mapped to \rightarrow etc, (not
\xrightarrow). We can talk about including style variants for the
mappings.
