Regular Expressions
Mastering Regular Expressions; Powerful Techniques for Perl and Other Tools, Jeffrey E. F.
Friedl, O'Reilly, 1997, ISBN 1-56592-257-3

Covers how Unicode characters fit into a regular expression language. The simple answer is "about
the same as you'd guess," but this has the formal details.
