Re: regexp for unicode control chars

[Raj Chak]

Thank you for the detailed explanation, Rick.

I am using UTF-8 character set.

SELECT * FROM tbl WHERE HEX(msg) RLIKE '^(..)*C3'; works fine.

My objective was to find a mysql equivalent of the java regex expression:
\p{C}
That matches invisible control characters and unused code points.

Thanks again.
