Regex on Create Character and Name change allows _ in names

[tysonstrange]

Users are able to create characters and/or rename their characters names to include or simply be a bunch of underscores.

It's using this regex pattern

"/^[a-zA-Z_ ]+$/"

This allows A to Z, Underscores and "spaces" in names.

Is this intentional?

Looks like this is also present in Guild names

certainly not intentional
