Until 5.1.0 is published, the most up to date list of characters with
the "soft_dotted" property is
In it you will find 45 characters listed that have the soft-dotted
behavior, but they do not include the combining i. The reason for that
is that in Unicode, you can't apply a diacritic to a diacritic, you can
only apply a diacritic to a sequence.
Diacritics may then interact typographically, but ordinarily, if you
apply a macron to a character with a diacritic the macron is not applied
to that diacritic. So, it would seem that if an 'i with macron'
diacritic is needed, that is something that is not encoded yet.
A macron applied to a sequence of <e , combining dotless i> should be
rendered as if it applied to the whole. It, what the notation tries to
express, is the modification of an 'e' by an i-macron, then the
combining character that is missing would be the i-macron.
As to whether that character should be encoded, I'm neutral - you would
need to demonstrate that its use matches the type of precedent for which
the other superscripted combining letters were encoded.
It appears that phonetic notations are about the most demanding when it
comes to character encoding. Even mathematics pales in comparison ;-)
