Hi Unicode mailing list,

I'd like to know if Unicode is able to incorporate infinity subscripts into the specification? This would help with mathematical notation as it is very common there to mark some limiting behavior of a sequence.

Some internet discussion here:

https://communities.sas.com/t5/SAS-Programming/How-to-create-a-subscript-of-the-infinity-symbol/td-p/738302
https://www.reddit.com/r/Unicode/comments/zgchk6/subscript_infinity_symbol/

Some programming languages like Mathematica (https://stackoverflow.com/questions/5481216/subscripted-variables) benefit from numbered and variable name (such as x, n) subscripts for other functionality, and infinity would help with this.

Many thanks,
Andrei
