But still, all the other related symbols are multipurpose and cannot

be fixed. They are still usable including in maths contexts, even if

their rendering is not always adequate for maths (where they may

become confusable).

But still these other characters should not need to take maths into

consideration, so the MIDDLE DOT 00B7 should still behave correctly in

Catalan as a diacritic and as a punctuation, and should remain:

- between the middle of the M-height and the middle of the x-hieight

(for correct display after l/L, or as a punctuation);

- but not on the middle of the math line like 22C5 (along with the

mathematic MINUS sign and the PLUS sign, the same center used as well

for the x-shaped multiplication sign, the division sign... all these

maths symbols having more strict presentation constraints).
