I see a big problem here: why would the Unicode Standard take a position
on mathematical use in a manner that strongly conflicts with the ISO and
IEC standard on mathematical notations? The ISO 80000-2 standard (also
issued as IEC standard) designates U+003A as a character used for ratios.
What I have proposed, regarding COLON, is just
* also used to denote division or ratio
I don’t think RATIO needs an annotation, as the name reflects the
intended usage. But if an annotation is added, it could be e.g.
* used to denote ratio (e.g. in a scale), as an alternative to 003A COLON
