[Pkg-haskell-maintainers] Bug#702617: . fails to match certian characters

[Joey Hess]

Package: libghc-regex-compat-dev
Version: 0.95.1-2+b1
Severity: normal

Prelude Text.Regex> matchRegex (mkRegex $ "^.*$") "o"
Just []
Prelude Text.Regex> let s = "ò"
Prelude Text.Regex> s
"\242"
Prelude Text.Regex> matchRegex (mkRegex $ "^.*$") s
Nothing
Prelude Text.Regex> matchRegex (mkRegex $ ".") s
Nothing

I mentioned this to upstream and he said:

| That looks like it is pushing the unicode text to your system C library for
| matching.  This translation is probably making a multibyte C-string and then
| running a non-Unicode aware C-library call.
| 
| You will need to check your setup.
| 
| It is true there are some bugs in this, but they are in the translating of
| indices, which does not apply here.
