The following assumes that names are only valid if they contain ASCII letters, hyphens or apostrophes. However, the first or last character of a name can't be a punctuation character and a name must be between 1 and 20 characters long. A single character name is allowed to cater for an initial where the full name is not known. People are given a chance to abbreviate their names if they are too long.
