Thanks.  Will the correction be rolled out to all Microsoft
Windows 10 customers at about the same time?  I appreciate that
corporate customers may impose their own extra, internal delays - my
employer is still on Windows 7.

In the meantime, I've updated my fonts (Da Lekh and Lamphun) to
correct the problem.  However, such corrections run the risk of wrongly
deleting dotted circles that come from the backing store, and so are
not Unicode-compliant.  The sooner I can remove the corrections, the
better.

I had the impression there were more overrides than just those.

That seems welcome news.  I still don't know what the problem with
supporting them has been.

Richard.
