I'm building a CMS for a scientific journal and that uses a lot of Greek characters. I need to validate a field to include a specific character set and Greek characters. Here's what I have now:
[^a-zA-Z0-9-()/\s]
How do I get this to include Greek characters in addition to alphanumeric, '(', ')', '-', and '_'?
I'm using C#, by the way.
