Hello.
It seems that the regex-pcre has a bug dealing with utf-8:
I hope this bug can be fixed soon.
Is there a bug tracker to report the bug? If so, what is it?
You need something like that
let pat = makeRegexOpts (compUTF8 .|. defaultCompOpt) defaultExecOpt 
("@'(.+?)'@" :: B.ByteString)
and than pat will match correctly.
The bug is related to String (not ByteString) in a UTF-8 locale.

Until it is fixed, I am using the workaround of converting the regular
expression and the text to ByteString, doing the matching, and then
converting the results back to String.
