names ending in . are "not properly normalized" but error message suggests they ought to be

<<< Name should be less than 13 characters and only contains the following symbol .12345abcdefghijklmnopqrstuvwxyz
Error Details:
Name not properly normalized (name: nev5alcoxwj., normalized: nev5alcoxwj)

Either the error message is inaccurate or the error is erroneous: The name nev5alcoxwj. is 12 characters taken from the allowed alphabet.

This 11 character name fails, too: gznbv2ukpu. as do other even shorter names ending in . -- so that's the issue: names ending in . result in the above error apparently independent of the name's length.

[heifner]

Names ending in '.' are not allowed.

[kkurian]

@heifner Apparently... but that is not at all clear from the error message. Consider updating the error message?

[heifner]

What would you suggest?

[kkurian]

"Name must be less than 13 characters, not end with a period, and only contain the following symbols .12345abcdefghijklmnopqrstuvwxyz"

I’m receiving this error message. How can I properly normalize my name? It’s the name eosio assigned me in 2018
