I think that strings that contain Unicode characters are incorrectly matched. For example, using regex-pcre in ghci gives us unexpected result:

> "Č123456" =~ "4" :: (String, String, String)
("\268\&1234","5","6")

Similar example without Unicode characters produces expected result:

> "C123456" =~ "4" :: (String, String, String)
("C123","4","56")

Tested with regex-pcre 0.95.0.0 and ghc 8.6.5

I should add that libpcre installed on my system is working fine.

This bug is probably related to incorrect matching of strings that contain unicode.

Does this package support PCRE2? Reading the code I can’t see any reference to PCRE2. Do you have any knowledge of another Haskell package with pcre2 support?
