I'm not aware of a distribution that still allows selecting a non-UTF-8
charset in a normal flow in their installer. And if they haven't purged
support for ancient encodings, that support is thoroughly bitrotten.
Thus, I disagree that this is a legitimate concern.
What _could_ be a legitimate reason is that someone is on a _terminal_
that can't display a wide enough set of glyphs. Such terminals are:
• Linux console (because of vgacon limitations; patchsets to improve
other cons haven't been mainlined)
• some Windows terminals (putty, old Windows console) that can't borrow
glyphs from other fonts like fontconfig can
For the former, it's whatever your distribution ships in
/usr/share/consolefonts/ or an equivalent, which is based on historic
ISO-8859 and VT100 traditions.
For the latter, the near-guaranteed character set is WGL4.
Thus, at least two of your choices seem to disagree with the above:

× is present in ISO-8859, V100, WGL4; I've found no font in
/usr/share/consolefonts/ on my Debian unstable box that lacks this
character.
⬍ is not found in any of the above. You might want to at least
convert it to ↕ which is at least present in WGL4, and thus likely
to be supported in fonts heeding Windows/Mac/OpenType recommendations.
That still won't make it work on VT.
Meow!
