I oppose your argument of "garden-variety" type symbols because consistancy
of this usge with a defined pattern is not demonstated, included in the
precise domain where they are found.

[1] The first part is a good real-life expression of what is meant by
abstract character and the fact that we don't encode glyphs. So this is not
so much a novelty (this is stated in the standard that we don't encode
glyphs but only abstract characters independantly of orthogonal styles and
tools used to render them).

[2] The second part is the expression of the exceptions that have been made
ONLY because there REALLY was a well-defined pattern of usage where the
additional meaning of a precise style is consistant (and really HAD TO
be)... Allowing then these exceptions (the other exceptions have been for
interoperability with older character sets for terminals that had almost no
graphic capabilities). So this is also not a noverlty.

For now we lack the evidence of a consistant meaning in any given domain
(not too much specialized to a single source at a single place for this
