Here is an example.  Emacs' ipa input method supports, eg, a
miniscule open e w/ tilde.  The bdf fonts in the gnu unifont
collection includes one w/ the xlfd:  (also in 14 and 24 pix)

-etl-fixed-medium-r-normal--16-160-72-72-c-80-muleipa-1

that contains the open e w/ tilde as a single character (encoded at
0xbb).  In unicode, however, there is no precomposed character for
that; one must use U+025B LATIN SMALL LETTER OPEN E and U+0303
COMBINING TILDE for that.  That is, in utf8, < ɛ̃ >.

He wants to be able to use a font like the muleiap-1 fonts to display
such combining sequences.

(muleipa-1 also has tilda'ed versions of latin small letter alpha,
latin small letter open o and latin small ligature oe that are also
not precomposed in unicode.)

(NB that muleipa-1 was just the first example I thought of; it is
probably not the one the OP is using, merely similar.)
