I have to disagree. The issue is about *any* technology that can be
used to convince the user that one URL is being accessed when in fact
another one is.
Whether one should try to warn the user is a separate question, which
depends on the probabilities of legitimate vs. fraudulent displays,
and the cost of annoyance vs the *avoidable* cost to fraud victims.
Unfortunately, the HCI evidence suggests that few potential victims
listen to warnings (or even understand them), so you're probably right
that it's a bad idea to warn if RTL characters are present.

If you mean the controls, you're probably right, although RFC3987 has
been updated for international domain names. I suppose those controls
are not permitted, though.

OK, good enough for me.

Whatever the display would be in the absence of an attempt to detect
and warn about instances of possibly fraudulent use of directional
controls.

The best I've been able to come up with given the unfortunate conflict
between UAX#9 and the "normal" display of URLs as I understand it is a
one-off warning (or use of something like the novice mechanism so the
user can easily "turn it off" as defined above as soon as it becomes
annoying -- I expect your judgment to be that it would *always* be
annoying, just mentioning the possibility for completeness).

Unfortunately, besides LTR in RTL control, and RTL in LTR control, I
can't help, not being familiar with the expected display.
