Yup, that did it. And you're right, you don't need to escape
the '.'.
So the extra \ is needed because of the single quotes string.
Arrrrgggg..... :-)
Thanks Steve !

Try:
E'^[a-zA-Z0-9._\\[\\]]+$'
The "outer" level of parsing turns that into '^[a-zA-Z0-9._\[\]]+$'
which is the regex you want. Also, I'm *pretty sure* you don't need to escape
the '.' within a character class.
Cheers,
