New issue 130: Some characters in filenames cause the indexing to fail

Samuel Delisle:

While creating the index necessary for full-text search, it looks like filenames with special accented characters (è, à, é, ...?) within a repository cause an exception.

Here's the output of the command: `/opt/kallithea/venv/bin/paster make-index /opt/kallithea/data/production.ini`

```

This is using Kallithea 0.2.1 on an Ubuntu server (running through VirtualBox, but that shouldn't change anything?), using Mercurial repositories.
