[Exist-open] xmldb:collection-available not reporting existence of collection named "Å"

[Henrik N. <hen...@gm...>]

http://localhost:8080/exist/rest/db/apps/irhb/?_query=xmldb:collection-available(%22/db/apps/irhb/data/originators/A%22)

*returns*

<exist:result xmlns:exist="http://exist.sourceforge.net/NS/exist" exist:hits
="1" exist:start="1" exist:count="1" exist:compilation-time="1"
exist:execution-time="1">
<exist:value exist:type="xs:boolean">*true*</exist:value>
</exist:result>[,]

*but*

http://localhost:8080/exist/rest/db/apps/irhb/?_query=xmldb:collection-available(%22/db/apps/irhb/data/originators/Å%22)
<http://localhost:8080/exist/rest/db/apps/irhb/?_query=xmldb:collection-available(%22/db/apps/irhb/data/originators/%C3%85%22)>

*returns *

<exist:result xmlns:exist="http://exist.sourceforge.net/NS/exist" exist:hits
="1" exist:start="1" exist:count="1" exist:compilation-time="0"
exist:execution-time="0">
<exist:value exist:type="xs:boolean">*false*</exist:value>
</exist:result>[.]

I did create the collection "Å" and can confirm its existence as well as
access documents in it via eXide and oXygen.

Wrapping the parameter of xmldb:collection-available in util:unescape-uri(
, "UTF-8"), xmldb:decode() or xmldb:decode-uri() doesn't help. Replacing
"Å" in the URL with "%C3%85" also doesn't do the trick. How can I make
xmldb:collection-available
recognize the collection and others with name outside the a-z, A-Z ranges?

Any help would be much appreciated,
