HarfBuzz is remarkably compatible, and its version until now was never
important.  I asked about that because it is the source of the
composition data which seems to be incorrect in the wrong display

Thanks.

One more question: what is the value of current-iso639-language, and
is it different between the "bad" and the "good" cases?
