Fixed by checking for the negative return value of _Xlcwctomb and
returning 0/XLookupNone in that case.
Unfortunately the other return values for *status don't fit into the
error (which appears to indicate some internal error or running out of
memory). The other valid status codes are XBufferOverflow,
XLookupNone, XLookupChars, XLookupKeySym, and XLookupBoth. Each of
these has a specific meaning attached.
