that is ingenious! Thank you very much!

The patch works just fine except for one thing; the change in the ruby
adapter needs to read something like this:
  |     full_args << '--config' << "redminehelper.fileencoding=#{path_encoding}"
because using '<<' to add the path_encoding variable causes ruby to add a
space in front of -- in my case -- 'UTF-8' ultimately leading to this
error:
 | hg: unknown command 'UTF-8'
 | (use 'hg help' for a list of commands)

Except for that, everything works just fine! Thank you very much! :)

all the best,
    Adi
