(in both versions)
I assume that hledger-0.7 is built with ghc-6.10 and that you built 0.8 with ghc-6.12. Without looking at the code, this is what happening most likely: The hledger code did not actually change. In both instances in transforms unicode characters into UTF8-encoded byte sequences (still represented as [Char]), and prints them using "putStrLn". ghc-6.10 would print these byte-for-byte, and they turn up correctly on your computer. ghc-6.12 is smarter and transforms them to the local locale, in your case, UTF8. The effect is what you see: double-encoded UTF8 strings. So this is not a bug in ghc, but a bug in hledger that turned up due to the (thankfully) more sensible behaviour in ghc. You need to talk to the hledger maintainer if he already has code that works with ghc-6.12.
