I can't comment on that, I have never seen a letter Dal in use. I just
picked it up blindly from Justins paper.

Same comment.

Yes, I wanted to raise the same question. I *have* seen them being
mentioned once in the mail archives, but I don't remember by whom.

I have not seen this one either, so I don't know how it is supposed
to look like, but I have picked up the following information in a posting
to comp.text.tex some time ago:

:I would like to write a short citation of a greek word, without
:using a babel package. The TeX Book advises to use math mode.
:
:Actually, that's fine, except for the beta, when it's used inside
:a word ($\beta$ is only correct for initial letters).
:The correct beta (a \varbeta ?) should look like a mirrored $\partial$

Since we're counting slots here, let me mention another idea of mine
which would buy us 1 slot per encoding:
Since we have decided to have a space in slot 32 in every encoding,is it really necessary to reserve slot 0 as skewchar ? Is there any
reason against using slot 32 as the skewchar ? No glyph will ever have to
be kerned against the space, or am I wrong here ? And the dumb drivers
which rely on the space in slot 32 (are there any ?) will never see the
kerning, if they ever see a space glyph at all.
