Summary of the Pull Request

Up to now we've using U+2E2E (reverse question mark) to represent the
SUB control glyph. This PR changes the glyph to U+2426 (substitute
form two), which is also rendered as a reverse question mark, but is
more semantically correct.

References and Relevant Issues

The original SUB control rendering was implemented in PR #15075.

Validation Steps Performed

I've manually confirmed that printf "\x1A" is now shown as a reverse
question mark in OpenConsole when using the Cascadia Code font. That
would not previously have worked, because U+2E2E is not supported by
Cascadia Code.

Up to now we've using `U+2E2E` (reverse question mark) to represent the
`SUB` control glyph. This PR changes the glyph to `U+2426` (substitute
form two), which is also rendered as a reverse question mark, but is
more semantically correct.

The original `SUB` control rendering was implemented in PR #15075.

I've manually confirmed that `printf "\x1A"` is now shown as a reverse
question mark in OpenConsole when using the Cascadia Code font. That
would not previously have worked, because `U+2E2E` is not supported by
Cascadia Code.

Closes #16558
