Until this proposal, the last times I saw a capital letter AT was as a
symbol, with probably the same meaning as the classic commercial AT. I
thought it was just a presentation variant.
Well, with this proposed new character, texts may now use this capital
letter as a symbol as well, without depending on presentation forms that may
be present in some fonts. It would not change its property as a capital
letter, as this choice of usage would be left to the author (after all, the
ASCII period has many usages too...)
The only good question is: does a font need to show a visible difference for
the lowercase letter at and the existing commercial at symbol? Probably not,
unless the current design of the symbol in an existing font does not fit
well with the design style of other latin letters (but the provided
documents snapshot are not exhibiting a unified design style for the at
letter and the other latin letters (notably for the slanting angle of the
lowercase at letter, or the glyphic presentation of its "embedded" letter a
with a single eye instead of two eyes for the normal latin letter a).
Couldn't there exist two presentation forms for lowercase letter at, like it
is for lowercase letter a ?
As a subsidiary question, are there languages that make a distinction
between the one-eye and two-eyes forms of lowercase letter a (U+0061)? If
so, how is their uppercase versions ?
