Description Myles C. Maxfield 2020-07-21 21:27:18 PDT 
From static void overrideControlCharacters() in Font.cpp:

overwriteCodePoint(narrowNoBreakSpace, zeroWidthSpace);

This is bogus.

Also, this is becoming much more prominent now because a lot of the French unit formatting data in CLDR - and hence in e.g. NSMeasurementFormatter - uses 202F between numeric value and unit, e.g. "37 km"

It works in native content on macOS, and in all other browsers on macOS, but not in WebKit.
