@ -145,12 +145,22 @@ scripts mentioned in section 5? For Confusable Detection, it seems one
needs two identifiers to compare them for confusion - is it possible
to somehow apply it to a single identifier only, and warn?
In follow-up discussion, it turns out that John Nagle actually
meant to suggest UTR#36, level "Highly Restrictive", [3]_.
Several people suggested to allow and ignore formatting control
characters (general category Cf), as is done in Java, JavaScript, and
C#. It's not clear whether this would improve things (it might
for RTL languages); if there is a need, these can be added
later.
