That's not how this stuff works in RTL locales.  It works by changing
the character produced by the keyboard keys assigned to these
characters, when the keyboard is configured for an RTL language.
E.g., a key labeled « should produce » when the current language is
RTL.  That's how this works with mirrored characters as well, because
when you type in an RTL language, you will press ) when you want an
opening parenthesis, since that's what you expect to see on display.

With a suitably configured keyboard (or input method, for that
matter), the problem you mention doesn't exist, and therefore there's
no relation between whether characters are swapped and whether they
are mirrored.
