Collectionfilter unicode error

I have a 5.1.5 site with c.collectionfilter that sorts on 'contributors'. I have a problem with one of the names – his middle name contains the norwegian character 'ø' - so for now, I have just 'dropped the middle name'.

Does anyone have code (for the indexer ?) that works with c.collectionfilter ?

If not: where would be the right place

There was a bugfix in collective.collectionfilter which may be relevant to your use case: Fix bug where filter urls was getting utf encoded then made into unicode again [djay]
Described here: collective.collectionfilter/CHANGES.rst at main · collective/collective.collectionfilter · GitHub

I see that I have 3.2.1 installed, but I tested 3.5 and 3.1 and both produced the same error.

Maybe the solution could be to 'use unicode instead of ascii' for the contributors index ?

If the list of contributors is not giving you issues in other situations (e.g. tags on the document itself), then I would look at the values the querybuilder is passing to the search catalog. This will help you find out where the error is taking place.

Have you tried upgrading to Plone 5.1-latest :wink: These types of corner cases have a tendency to magically disappear in later versions.

It it on a live site, so I dont really want to change too much unless I have to, so I will need to test it on a copy ( or wait until the teachers of that school go on strike, probably in a few days :slight_smile: )

Update: I did a check and see that the Subject index works without unicode error. A bit strange, maybe, since they both use Keyword index (and I though both are unicode indexes)

Update 2: This is even stranger (?). I removed the Subject index, and indexed another field with the Subject index, and c.collectionfilter does still show the 'the (right) Subject values in the portlet. (It is not a caching issue, I made a new ).

To me, the value that is passed for "Subject" and "contributors" is exactly the same ( both show 'query': '\xc3\x86\xc3\x98\xc3\x85', but only 'Subect' works, so I have a feeling something else is going on)
