Removing characters for obscenity is pointless (thousands way to evade this "filter"), english-centric and honestly a weird idea.

I've always heard that the reason in another ambiguity (u/v) which makes more sense to me.

Base64/Base32/ASCII is English-centric.

Might be weird to you personally, but there's literally government agencies to prevent obscenities.
