Subject: [PATCH] Fix validation rejecting all NAME and TEXT attrs
When the UTF-8 validation loop finishes successfully, `*ptr` points at
the `'\0'` at the end of the string. The code misinterpreted this as a
control character (`*ptr < ' '`) and failed the validation.
Fixes https://github.com/apple/cups/issues/5325
