CQ 5 Tag Search with German special characters

Question

Hi all,
I configured CQ 5.5. to do search on a set of custom tags that I created for documents. I did that by adding some new tags in /etc/tags/custom and adding this path in /apps/dam/content/search/searchpanel/facets/tagoptions. I noted that search works fine for any new tag that I created except those tags which contain German characters like küche. Can anyone help here on what could be the issue ?
Thanks!

I see your point. Got exactly the same problem in the DAM when searching for "ökologische" but "Unternehmenskonzept" that is in the same document is found.
When sending "ökologische" from QueryDebugger, it searches for:
18.06.2013 16:15:23.836 *DEBUG* [10.62.25.120 [1371564923836] GET /libs/cq/search/content/querydebug.html HTTP/1.1] com.day.cq.search.impl.builder.QueryImpl executing query (predicate tree):
ROOT=group: [
    {fulltext=fulltext: fulltext=%C3%B6kologische}
but from DAM Search
18.06.2013 16:17:16.096 *DEBUG* [10.62.25.120 [1371565036096] POST /bin/querybuilder.json HTTP/1.1] com.day.cq.search.impl.builder.QueryImpl executing query (predicate tree):
ROOT=group: limit=15, hitwriter=full, nodedepth=4, offset=0[
    {fulltext=fulltext: fulltext=ökologische}
    {mainasset=mainasset: mainasset=true}
    {orderby=orderby: orderby=path}
    {path=path: flat@Delete=true, path=}
    {type=type: type=dam:Asset}
    {0_daterange=daterange: lowerBound=, property=jcr:content/jcr:lastModified, upperBound=}
    {1_group=group: or=true[
        {property=property: property=jcr:content/metadata/dc:format}
    {2_group=group: or=true[
        {property=property: property=jcr:content/metadata/cq:tags}
    {3_group=group: or=true[
        {property=property: property=jcr:content/metadata/dam:scene7FileStatus}
even if I can see that the JSON structure sent to /bin/querybuilder.json is:
p.hitwriter=full&p.nodedepth=4&mainasset=true&type=dam%3AAsset&fulltext=%C3%B6kologische&path=&path.flat%40Delete=true&orderby=path&0_daterange.property=jcr%3Acontent%2Fjcr%3AlastModified&0_daterange.lowerBound=&0_daterange.upperBound=&1_group.property=jcr%3Acontent%2Fmetadata%2Fdc%3Aformat&1_group.p.or=true&2_group.property=jcr%3Acontent%2Fmetadata%2Fcq%3Atags&2_group.p.or=true&3_group.property=jcr%3Acontent%2Fmetadata%2Fdam%3Ascene7FileStatus&3_group.p.or=true&p.limit=15&p.offset=0
This is on a CQ5.5-system.
