It is, in fact, equivalent to a single underscore. This is reasonable, given
the unicode rules [I assume identifier lookup uses NFKC] and how these
characters function for East Asian users.

Honestly, if I were to suggest any change it'd be to fix it so it's allowed at
the beginning of an identifier. Let each (human) language's community worry
about coding conventions for code intended for speakers of that language
instead of trying to impose things on the world as english-speakers.
>>> a=1
>>> a_b=2
>>> ａ
1
>>> ａ＿ｂ
2
