Hi Jonathan,

I've just noticed that catcodes of superscript i and n have catcode 11, as do the latin & greek subscripts. (Code points appended.)

I'm going to change this in unicode-math (so they're all cc12), but do you think this is something that should be changed in the ini file?

(I'll check this with LuaTeX, too.) 

The reason it's a problem is that users try to write things like $\Cⁿ$ and the expected behaviour, well, isn't.

Many thanks,
