This could be a bug in the Tool Shed, or in how planemo handles encodings?

```
[galaxy@ppserver pico_galaxy]$ planemo --version
planemo, version 0.24.0.dev0
```

``` bash
[galaxy@ppserver pico_galaxy]$ planemo shed_update -t testtoolshed tools/seq_filter_by_id/ -m "v0.2.3, ignore blank lines in ID file (contributed by Gildas Le Corguillé)"
cd '/mnt/galaxy/repositories/pico_galaxy/tools/seq_filter_by_id' && git rev-parse HEAD
cd '/mnt/galaxy/repositories/pico_galaxy/tools/seq_filter_by_id' && git diff --quiet
Could not update seq_filter_by_id
Unexpected response from galaxy: 500:
Internal Server Error

Internal Server Error

The server has either erred or is incapable of performing
the requested operation.

Repository metadata updated.
Failed to update a repository.
```

Workaround: Replacing the e-acute with a plain e:

``` bash
[galaxy@ppserver pico_galaxy]$ planemo shed_update -t testtoolshed tools/seq_filter_by_id/ -m "v0.2.3, ignore blank lines in ID file (contributed by Gildas Le Corguille)"
cd '/mnt/galaxy/repositories/pico_galaxy/tools/seq_filter_by_id' && git rev-parse HEAD
cd '/mnt/galaxy/repositories/pico_galaxy/tools/seq_filter_by_id' && git diff --quiet
Repository seq_filter_by_id updated successfully.
Repository metadata updated.
```

I would try the latest release planemo 0.25.1 except this development machine is still all setup to run Galaxy under Python 2.6 (and planemo has dropped support for Python 2.6).
