This appears to be another possible mistake. However, the Greek script
does
provide a context which could be used to select the "ano teleia"
appearance
and properties (unless you tell me that the character appears in Greek
surrounded by non-Greek alphabet characters).
And even this basic rule will be defeated in maths formulas where the
MIDDLE DOT 00B7 has been used as a common multiplication operator, along
with numbers and variables named after Greek letter. Of course Unicode has
now distinctive symbols for maths, but that's another story.
RIght, because 22C5 exists for that purpose.
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).
Nothing prevents a mathematical layout program from fine tuning the
display of 00B7 if used as a raised decimal point. (see other post).
