"It" would not be encoded, as Latin-based phonetic alphabets are
not encoded per se in Unicode.
The English Phonotypic Alphabet is one of a number of attempts
at developing a systematic phonetic alphabet, going back at least
as far as Benjamin Franklin, during the 18th and 19th centuries,
and culminating in the eventual standardization of IPA.
Most of the non-A-to-Z characters in the English Phonotypic Alphabet
shown in this book sample are already encoded as Latin letters
in Unicode. The few that aren't would be perfectly appropriate
as proposed additions to the Latin repertoire, if someone would
care to do the research and write up the appropriate proposal.
Note that there would be some casing issues for any proposal to
complete the set of characters needed for the English Phonotypic
Alphabet. Ellis was mixing up the need for an orthographic
reform for English with the need for a technical phonetic alphabet.
Thus the EPA maintains orthographic casing rules for English
and requires both uppercase and lowercase forms for each
letter. This is non-problematical in most instances, but in
those instances where Ellis adopted an unusual letterform in
lowercase, he apparently just invented fanciful uppercase forms.
This might not be an issue for some case pairs where both lower-
and uppercase are inventions, but for others the uppercase might
not match what one would expect.
For example, I would suggest U+1D8F, U+1D96, and U+1D99 for the
a, i, and u with right hooks, respectively, in the EPA. But each
of those has a fanciful uppercase form, and in the case of
the a with right hook, looks too much like an uppercase A-macron.
Also, the EPA definition uses a normal uppercase "A" as the uppercase
of the rounded-top-a (= U+0251) for the ash sound (IPA U+00E6), but
uses an invented rounded-top-A for as the uppercase of the normal
roman a (= U+0061) for the a sound (IPA U+0061).
Because of these kinds of oddities, any proposal for EPA letter
additions would have to pay some attention to casing -- and my
suggestion would be to eschew expectations of regular casing
for EPA letters. Expecting all EPA casing relations to be
encoded directly would lead to more confusing letter clonings
likely to be rejected by the UTC.
