Regex word boundary metachar is not working in a character set

Regex:

(?<=[a-z])(?=[A-Z])|(?<=[0-9])(?=[A-Z](?![_\b]))|(?<=[A-Z])(?=[A-Z][a-z](?![a-z]))

Error:

Any chance this could get implemented in a future release?

Re: Regex word boundary metachar is not working in a character set

No, "\b" is a zero-width assertion, it can't be inside a character set "[...]".

Try the alternation operator "_|\b".
