U+093b is still in the BMP. By the way, what text encodings for source files are supported by GHC? Escaping everything isn't fun. And I am not sold on lens-regex-pcre documentation; "anything that works in PCRE will work" comes across as very dismissive. What string-like types are supported? What version of PCRE or PCRE2 does it use?

> version of PCRE It uses https://hackage.haskell.org/package/pcre-light https://hackage.haskell.org/package/pcre-light , which seems to link with the system version. So it depends on what you install. With Nix, it will be part of your system expression, of course.

For example, pasting that character into GHC yields: ghci> mapM_ T.putStr ("foo bar ः baz" ^.. [regex|\p{Mc}|] . match) ः > What string-like types are supported? ByteString (raw byte arrays) and Text (Unicode, internal representation UTF-8), as you can see from: https://hackage.haskell.org/package/lens-regex-pcre https://hackage.haskell.org/package/lens-regex-pcre > What version of PCRE or PCRE2 does it use? Whatever your system version is. For me on Debian it's: Package: libpcre3-dev Source: pcre3 Version: 2:8.39-15
