I'm expecting a validate_format_of with a regex like this
to allow many of the normal characters like ö é å to be submitted via web form.
However, the extended characters are being rejected.
This works just fine though (which is just a-zA-Z)
So, what's the secret to using unicode character ranges in Ruby regex or Rails validations?
It also seems to fail with full \x0000 numbers, is there limit at \xFF?
