Problem with autocomplete and backslah in result

Problem with autocomplete and backslah in result

Hi,
 
I am having a problem with jqeury autocomplete, that the search result can't contain a backslash. The results are displayed properly in the dropdown, as example "abc/test", but as I hit enter or cklicking the result, the textbox turns empty. Results which doesn't contain a backslash are working fine.
 
Does anybody has an idea, whats going wrong? I don't think it has to to something with escaping, otherwise the results wouldn't be displayed properly.
 
Thanks in advance!
