Add test for issue1344046 and maybe issue1195739 Python3 should be properly indexing unicode words while python2 doesn't. Add test (xfail for python 2) for this. So far I have passing on python3 (tested 4 of 6 indexers) and fail on 2 of 6 and xpass on 2 of 6 under python2.

def audit_html_files(db, cl, nodeid, newvalues):
    if 'type' in newvalues and newvalues['type'] == 'text/html':
        newvalues['type'] = 'text/plain'
    

def init(db):
    db.file.audit('set', audit_html_files)
    db.file.audit('create', audit_html_files)
