Description

When I put underscore(_) in the identifier, for example "San_Zhang", it will report error when click save.

The following input errors were detected:
The identifier contains invalid characters.

I know this character is not allowed in DNS hostname, but it is allowed in e-mail address or account name.

underscore(_) should be allowed in the account name or the name part (prefix) of the e-mail address, not the domain suffix.

examples of valid:

San_Zhang

examples of invalid:

San.Zhang@example_host.com

Found this doc, but I am not sure if it is right one for this issue.
