Thanks for the reply. It’s very likely that the page contains images, borders,
background, etc., so I can recognize all the text are missing. But neither of
text missing nor text garbled suggests me how to fix it. I’d try another
browser, then give up viewing the page.
If it didn't suggest how to fix it to you before today, it should
suggest it to you today. If you get a bunch of fallback characters,
your first guess should be font problems. Anyone using scripts with
poor support, especially stuff stored in the PUA, will recognize right
off when the text isn't displaying.
I agree it’s nice if it suggests. The point of disagreement is that fallback
glyphs suggest nothing help to fix it to me, but apart from my personal
opinion, your opinion is taken and will not be disregarded when the CSS WG
discusses along with all others including agree and disagree.
Still looking for if there were any indication of security aspects of this
issue. If not, the CSS WG might discuss this as a user issue.
My thinking is that I would expect security issues in the display of
identifiers, but the examples should all be code points that are ruled
out as valid part of identifiers to begin with.
Similar issues might apply when displaying the text of legal contracts
or documents. Again, there should be dedicated techniques to secure them.
So, I fail to understand under what conditions this suggestion is "best
practice".
