Not a bug Invalid regular expression

[HolyK]

Affected version

2.0.0 RC2

I can not use following regexp for user registration. No idea why as it is a valid one.

^[a-zA-Z0-9]+$

Getting following error on save

Oops! We ran into some problems.
Invalid regular expression

EDIT: We have all tables converted to utf8mb4 and the config parameter is present. If that makes any difference.

Try this instead: /^[a-zA-Z0-9]+$/
