U+02EB and U+02EA come from the TCA submissions regarding
for Minnan and Hakka languages, for use with extended Bopomofo.
You can find examples in those documents. They are mixed
there with other Bopomofo tone diacritics. See WG2 N1713
for the initial submission. (1998-03-16)
Here is the scheme as represented there, with Taiwanese
Yin level (unmarked) tong1 'east'
Yin rising U+02CB (with Bopomofo glyph) tong2 'a surname'
Yin departing U+02EA tong3 'freeze'
Yin entering (unmarked) tong4 'supervise'
Yang level U+02CA (with Bopomofo glyph) tong5 'child'
Yang departing U+02EB tong7 'cave'
Yang entering U+02D9 tok8 'poison'
In Bopomofo these tone marks are typeset in a separate
vertical line to the right of the vertical line of
Bopomofo. In horizontal typesetting, they are either
over the top of the Bopomofo or set at the upper-right
shoulder of the Bopomofo character representing the
'final' of a syllable.
It is possible that they were originally designed by a
dyslexic based on the Chao tone letters, but no, they
are not really intended to be used as particular values
of those or as an augmentation of those tone letters. Instead,
as I indicated, they are used with another collection of
tonal diacritics for extended Bopomofo.
So no, they glyphs haven't been munged. But these obviously
need better annotation for the names list.
P.S. Is somebody collecting the 'Every character has a story'
