Unicode file content conversion

[Simon King]

Since you are converting from subversion, you probably need to inherit
from hgext.convert.subversion.svn_source, rather than
mercurial_source.

I imagine the command line would then look something like this:

  hg convert --source-type customsource svn://localhost HgWorkDit/custom1

Hope that helps,

Simon
