Enforce ASCII for first name / last name?

[n8kim1]

Realizing that everyone just uses ASCII for their email addresses, which have ascii-ified versions of their names. May as well enforce this too? Names aren't displayed publicly anyways -- they're only used for purposes in which we have to change to ASCII.

Dos this really damper inclusivity? Hopefully not -- again, name isn't really used anywhere anyways. Perhaps we can include an explainer or smth

Note that a backfill would be really tough...wondering if we should just make this a frontend-only change (thus slightly fake)
