Thanks for the suggestion, but that says:

"Tools used for command-line utilities:
	Cairo:			true
	Fontconfig:		true"

which rules that issue out.  An executable which I built, along with
the sharable libraries, on 12 September 2015 still works (once I
restored the absolute directory names - ouch!), and uses the sharable
object libcairo.so.

That version says fixes that I know fail on MS Edge should actually
work.  I presume it's out of date, because it rejects dependent vowels
on independent vowels, which are now in general allowed by USE;
Microsoft had previously stated that such independent vowels should be
reclassified as consonants.  (It's currently a convenient way of
checking which browser a PDF of a web page is derived from - MS Edge
allows them but Mozilla doesn't.  The test word is ᩐᩣ 'to take'.)

Richard.
