I don't understand this argument. It does not make sense to me.
(See also Ken's latest e-mail on this, where an example of the use
of epsilon for a linguistic "zero" is mentioned.)

In such cases it would be a terrible choice to use the EMPTY SET
character
for denoting a linguistic "zero" of any kind, since in print one may not
be able to distinguish one of the vowels from a linguistic "zero".

Then they are used as variables; not phonetic letters.

I have seen no indication that using U+00D8 for this would be an error.
(Not even from Ken, who otherwise provide excellent motivations; and
indeed provided another example where a letter (epsilon) is used for a
morphological "zero".)
