Showcase plugin makes Error 500 searches on tags containing special characters

[gsueur]

If the showcase plugin is loaded and you have tags containing special characters, like the french "é", you go into error 500 when you try to filter on this tag.
It comes from line 253 of plugin.py
fq = "{0} -dataset_type:{1}".format(search_params.get('fq', ''),
DATASET_TYPE_NAME)
which runs into UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 13: ordinal not in range(128)
I didn't find the way to fix it, sorry.

That sounds like #34 and should already be fixed (see #35). However, it seems that there hasn't been a release since then -- try using the latest version from GitHub. Perhaps @brew can prepare a new release 😉
