You either have to do that, or restrict usernames to ASCII subset only (and face the wrath of non-Latin alphabet users), or restrict to a whitelist of ranges that only represent alpha characters across all languages (i.e. not math symbols, nor box-drawing, nor emoji, etc.)

i8n is complicated because the diversity of language is itself complicated. I feel your pain, though, don't get me wrong.
