I'm having a problem adding references from Worldcat: it seems to be stripping unicode characters from the title string and replacing them with English-letter near-equivalents, which won't do.

Adding this:
http://www.worldcat.org/oclc/34553157&referer=brief_results
gives the title in Zotero as
O niepodleglosc i granice : 1914-1921
when it should be
O niepodległość i granice

I think it's a problem with the Worldcat translator because when I add the same book from the Library of Congress:
http://lccn.loc.gov/95141898
the title comes through properly as
O niepodległość i granice
(although I note that it does mess up the first author, putting them in as 1922-, (first).)

Well that sucks! Is this a problem with the RIS spec not properly supporting Unicode, or is this something where if I ask the right people at Worldcat nicely they might fix it for me? (Do you happen to know who those people are?)
