Hi

I attach a patch which does the quoting for real names but I don't know
if we want it: it changes (example taken from the test suite)

François Boulogne to

=?iso-8859-1?q?Fran=E7ois?= Boulogne

(which is what was in the original email)

Plausibly the best thing is just to leave the series as is, so the
text output is readable and parseable in the common cases.

Anyway the patch is attached if anyone wants to experiment.

Best wishes

Mark
