[Python-ideas] Allow using symbols from Unicode block "Superscripts and Subscripts" in identifiers

[Bruce Leban]

This block includes non-alphanumeric characters. You wouldn't want to allow
variables named

x⁺¹  (~ x+1)

Some of the characters in this block are already allowed (the letters in
category Lm). The characters you want are in the No (other numbers)
category. Unfortunately, adding that category would be problematic as it
includes characters like ½ and you surely don't want a variable named x½ or
x⑴. That's x1/2 and x(1) for those without Unicode fonts.

But when I write mathematical program with lots of indices I would like to use symbols from block "Superscripts and Subscripts" (as id_continue), for example:
