Are you asking to validate any pair of words that might be used as first and last names (so long as they don't contain special characters)? If so, what shall we do about first names taken from the language in question, but not commonly considered "names?" "Charity" might be an english language edge case; what if I named my nextborn "Broccoli?" And what do we do with the commonly accepted names in Spanish that do have accents -- I believe Jesús and María are common cases. I offer this hypothesis despite the seemingly contrary second sentence, which might be understood to mean that you want only to deal with names of languages. But you might wish to clarify your question.	[reply]

You can craft a regex (with Regexp::Assemble/Regexp::Trie/Regex::PreSuf) from data in modules like Locale::Country::Multilingual/Locale::Codes/I18N::LangTags::List	[reply]

so you want the first and last name to only contain allowable unicode characters, or only a subset of these characters in use in certain languages? if the latter, this would be most difficult, as there are many (unicode) characters that cross boundaries. if you're trying to do it the old fashioned way with the legacy ansi encoded extensions, it would still be quite hard. even harder if you wanted to make sure that first name character set (language) used matches the surname. especially that some people adjust their first names to match local language, say having emigrated. in the end you'll avoid difficulty just by boiling it down to something simple, like checking that both first and last name contain UTF-8 characters or such. the hardest line to type correctly is: stty erase ^H	[reply]
