Umm. Well, they aren't "double-wide" and they aren't "overstruck",
and their names are not:
> 035D: double-wide breve
> 035E: double-wide macron
> 035F: double-wide underbar (d-w combining low line)
but rather:
035D COMBINING DOUBLE BREVE
035E COMBINING DOUBLE MACRON
035F COMBINING DOUBLE LOW LINE
> Please send me more info (and some documentation) on those accents.
These would occur in sequences such as:
<o, combining double breve, o>
to give the effect of a breve stretched over a pair of o's, as
often seen in Webster-style dictionary pronunciation guides.
Technically, the combining double accents combine with the
base letter they follow, but their glyphs would be designed so
that they would overhang a following base letter as well.
In practice, fonts might simply choose to have ligatures for
the entire sequence, to avoid complications of calculating
the accent positions dynamically.
For more examples, just look in dictionary pronunciation guides.
