Encoding of new characters in not required to address the issue.
I agree. But annotations may help (these annotations should however be
narrowed by language where they are common, otherwise they will cause
other confusions...)
May be we could add new resources in the CLDR for specifying the
prefered characters used by the four basic maths operators (normally
we already have the specifiation for the uniary plus and minus signs,
but I'm not sure that this implies their use for noting the binary
operators used in additions

That's a lovely question...
Well if France isn't - Philippe Verdy says he has used '÷' for division

I would disagree about the preference for ratio; I think it is a historical
accident in Unicode.
What people use and have used for ratio is simply a colon. One writes 3:5,
and I doubt that there was a well-established visual difference that
demanded a separate code for it, so someone would need

Not really.

I am using the ratio character in the final 3∶5. Whether or not there is a
distinction between that and 3:5, and what that distinction is, seems to
depend entirely on the font in question.
Bizarrely, it does seem to have 3 dots in Lucida Sans.

The main point is that asserting a general preference in an annotation for ∶ to
express a ratio, as Asmus had in his formulation, is simply wrong and
counterproductive. (We are not going to change the world's usage from : to ∶
by fiat; and and the glyphic difference is quite subtle, and missing in

They are spaced differently. Attached how they are rendered by TeX,

That is, they *may be* spaced differently (depending on the font and
environment).
I'm not against pointing to RATIO for specific math contexts, but to tell
Joe Smith that he should be using a different character to say that the
ratio of gravel to sand should be 3:1 is artificial and pointless.
