For me, that's an en-dash (U+2013 / '\8211'). I believe something on your box mangled the UTF-8 encoding.

Weird I did a cabal install and have not touched it with an editor. Are you on Windows ? Aaron

Except to look at it trying to find the issue, I suppose (how else did you find the "–")? What's your locale? Could also be that GHC tries to interpret UTF-8 in your locale and barfs on that.
Are you on Windows ?
No, linux.

I downloaded it separately from the HackageDB.

Not sure ? Vista's default.

No, linux.
Ah How do I get Cabal to install a package from disk rather than from the internet ? Many thanks, Aaron

Which probably isn't UTF-8. There must be an analogue of locale on Windows to check.

Ah

If it's unpacked, just cd into the package directory and do a $ cabal install there (optionally provide further command line args, but not the package name) or $ runghc ./Setup.hs configure --user $ runghc ./Setup.hs build $ runghc ./Setup.hs install If it's a .tar.gz, I don't know if cabal already supports installing those from a specified location (i.e., not from hackage or its cache).
Many thanks,
Aaron

Not sure I thought it was UTF-8. Its behaving differently on different Vista machines.

No, linux.

When I saw this last night, I looked out of curiosity and saw the same thing, as my browser rendered the source with a dash. My thought was that this morning, someone would be embarrassed to see that he or she had gratuitously, but accidentally, made use of an exotic character when an ordinary 7 bit ASCII equivalent would have been fine and foolproof. I.e., it's a coding error, which we found out about thanks to Mr. Gray's platform encoding problem. Wrong again? Donn
Let's notify the maintainer to use an ordinary minus sign: http://hackage.haskell.org/package/ranges-0.2.3 my "scan" program (http://hackage.haskell.org/package/scan) reports: Ranges.hs:12:9: undesirable character '\t' Ranges.hs:12:51: undesirable character '\226' Ranges.hs:12:52: undesirable character '\128' Ranges.hs:12:53: undesirable character '\147' Cheers Christian Am 22.01.2011 18:33, schrieb Donn Cave:
