[Nepomuk] [BUG] with filex files

[Ignacio Serantes]

I have a method named toN3 with next code:

*def toN3(url = ''):*
*    if url[0] == '^':*
*        result = '^' + QUrl(url[1:]).toEncoded()*
*
*
*    else:*
*        result = QUrl(url).toEncoded()*
*
*
*    return result*

but is not working with "?" and the next change is required to query for
files like "test?.txt"

*    return result.replace('?', '%3f')*

Any other know exception?
