922,“lexical error (UTF-8 decoding error)” in WIndows 7,hamukazu,,"==== Symptom ====
When I type
> cabal install cabal
it fails with the following error:
> Distribution\Compat\Exception.hs:0:4: lexical error (UTF-8 decoding error)

==== Environment ====
It happens with 64 bit version of Windows 7.

It came to occur after I failed to install HXT. (I am not sure it is related.)

==== Workaround ====
By setting
> set LANG=C
in command line, cabal comes to work.

I regard this is just a workaround and this issue should be reported as a bug.
