One workaround for Wine is to copy Segoe fonts (Segoe UI symbol for this code point) to Wine.
Unity Editor manual mentions "hard-coded global list of fallback fonts" but does not tells the exact fonts.

AFAIK Segoe fonts are not free font, so usually modders should not distribute it.
If Wine user is unable to get Segoe fonts, it should be possible to config Wine FontLink as substitue. (I didn't test it)
