The obvious difference between all those video symbols and the CC button
is the CC button has language-specific characters in. Coming at this
problem from a different angle, a universal icon that doesn't have letters
in it would be a Good Thing, and would work in the proposed scheme. I have
seen such a thing, but I'm not sure how common it is.

For example this:
which I found from: https://learnoasis.com/improving-your-listening-skills/
but which does seem to be the closed caption icon used by YouTube.

The fact that YouTube has adopted a universal symbol is probably a Good
Thing that others would do well to follow. I've seen alternative versions
along the same lines in other apps too.

It might then make sense to assign a Unicode code point to such an icon as
proposed, and that would solve all these localisation issues too.
