For web requests wreq has a nice interface. The openssl bindings come from a different library so it does need an extra config line, the wreq docs have this example:
import OpenSSL.Session (context)
import Network.HTTP.Client.OpenSSL
let opts = defaults & manager .~ Left (opensslManagerSettings context)
withOpenSSL $
getWith opts "https://httpbin.org/get"
There are native Haskell tls implementations that you could plug into the manager config. But openssl is probably the more mature option.
"Cute" comes across as very dismissive. I'm not sure if you intended that. lens-regex-pcre is just a wrapper around PCRE, so anything that works in PCRE will work, for example, from your Mozilla reference:
I think in general that Haskellers would probably move to parser combinators in preference to regex when things get this complicated. I mean, who wants to read "\p{Sc}\s*[\d.,]+" in any case?
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?
I'm sorry, I don't know what that means. If you have a specific character you'd like me to try then please tell me what it is. My Unicode expertise is quite limited.
> I am not sold on lens-regex-pcre documentation
Nor me. It seems to leave a lot to be desired. In fact, I don't see the point of this lens approach to regex.

Noted, thanks, and apologies. That was not my intention. I was trying to make a statement of fact in response to your question.
> By the way, what text encodings for source files are supported by GHC?
UTF-8 I think. For example, pasting that character into GHC yields:
It uses 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.
Either hackernews or autocorrect ate the p, it was supposed to be \p{L} which is a unicode character class.
As the other comment mentioned pcre-compatible Regex are a standard, though the pcre spec isn't super readable. There are some projects that have more readable docs like mariadb and PHP, but it doesn't really make sense to repeat the spec in library docs https://www.php.net/manual/en/regexp.reference.unicode.php
There are libraries for pcre2 or gnu regex syntax with the same API if you prefer those
