Result: FAIL


I got stuck fixing these in Util.pm, because the decode function from Encode returned only a substring from the non-utf8 input (10sanitize_text.t) rather then the full string. I couldn't figure out if that was a bug (probably since the documentation claims it just replaces invalid characters) or a missing argument the function needs to be invoked with.
