  This system supports the C.UTF-8 locale which is recommended.
  You might be able to resolve your issue by exporting the
  following environment variables:
  
      export LC_ALL=C.UTF-8
      export LANG=C.UTF-8

Shouldn't LANG=C be supported by everything?

This is kind of a problem for scripting use of wormhole, when any
translations of the output need to be avoided. While C.UTF-8 is
available in recent versions of Debian, I doubt it's available widely
elsewhere. For example, it's not available on OSX.
