works as intended When attempting to create "pһuϰsᑯeν" sub, error message insists that it's not "alphanumeric". Technically it is, it's just not typable. Message probably ought to be clarified.

This should clarify a bit: https://stackoverflow.com/a/8202313 https://stackoverflow.com/questions/13233076/determine-if-a-unicode-character-is-alphanumeric-without-using-a-regular-express https://www.electrical4u.com/alphanumeric-codes-ascii-code-ebcdic-code-unicode/ >The most common alphanumeric codes used these days are ASCII code, EBCDIC code, and UNICODE And so on. If you don't agree, we can do a little boxing, winner decides.
