Yesterday I downloaded latest raspbian wheezy, installed it with HG on my second RPi. The result is HG running with mono 3.2.8 and there's no such issue. Go figure out why.
Which locale have you set?
Type the "locale" command and paste the output here.
$ mono --version

it would be also useful if you'd post the HG log. Always useful.....
