Advice on how to validate names and surnames using regex

Question

I want to validate name and surname for my Ruby on Rails 3 application and so I have posted this question. Someone adviced me to read the Falsehoods Progra

Answer 1

The correct way to validate names is:

1. Accept any and all possible Unicode characters.
2. Reject inputs of length 0.
3. Make sure the result has at least one character that is neither of type \pM, \pZ, nor \pC; i.e., is neither one of the combining marks, separators, nor other (usually control) characters. A character class like [^\pM\pC\pZ] should suffice.

There: easy as can be. You will probably need Ruby 1.9 to do this properly, though.
