Filtering to a certain language's alphabet is neither necessary nor
sufficient for a domain registrar. They're going to implement their
own system paying attention to http://www.unicode.org/reports/tr36/
(see particularly section 2.3 for why even a restriction to one script
doesn't keep them safe), so they don't justify keeping an attractive
nuisance in the standard library.
