Comment:
I understand a bit more about what is going on here. I removed `cabal-
install` from the equation by using `Setup.hs` instead. What happens is:
`ghc-pkg` is trying to emit a warning that the Haddock interface doesn't
exist (because I didn't generate it).
`ghc-pkg` is a subprocess invoked by Cabal, and as such is not attached to
the console. It therefore doesn't get the console's code page, and at
least on my system it then defaults to CP 850 (I had the console set to CP
65001, i.e. UTF-8). In CP 850 the Unicode chars in the directory cannot
be printed, so `ghc-pkg` fails when trying to print the warning.
Cabal then tries to read the output generated by `ghc-pkg`, but since
Cabal is attached to the console it is using UTF-8 and so misinterprets
the output generated by `ghc-pkg`, leading to more errors.
I don't think there's actually anything ''wrong'' here. Why it wasn't
failing before I have no idea. To work around it there are several
options:
* Don't create directories containing characters not in the system code
page
* Don't use `chcp` to set the console code page differently from the
system code page
* Run `cabal haddock` to generate the right files and stop `ghc-pkg`
complaining
