Note that those are not IPA symbols per se, but are part
of Extended IPA, and more specifically a collection of symbols
defined by the International Clinical Phonetics and Linguistics
Association (ICPLA).

They are not encoded in Unicode as characters per se.
Note, however, that they can be represented simply by using
superscript forms of:
U+0126 LATIN CAPITAL LETTER H WITH STROKE
U+0153 LATIN SMALL LIGATURE OE
And that is in fact exactly how they are already represented, for
example, on the Extended IPA Wiki page:
http://en.wikipedia.org/wiki/Extensions_to_the_IPA
Because Extended IPA involves a number of conventions that
are not necessarily amenable to plain text representation,
including ballooning of unvocalized text, parenthesized
diacritics, and subscripted italic expressions adopted
from musical notation, it isn't entirely obvious that
all symbols from Extended IPA (including these two) are
self-evident candidates for separate encoding as characters.
The case would need to be made -- and it would help if
the IPA and/or the ICPLA came knocking with a case to
be made regarding data representation, for which rich
text representations (i.e., using the superscripts of
existing characters) would not suffice.
