 | A bit out of my line of fire but I was wondering whether the
 | "Deutsche Schrift" letters, 'german fraktur hand forms' have been
 | suggested/mentioned for an inclusion? In Germany, a vector (in
 | mathematics) can be either written as a latin letter with a
 | superscript arrow, or alternatively, with a 'german letter' (see
 | attachments). Apart from that, it's still legal to use this form of
 | handwriting, even though few people use it.

   I have also seen these forms used as propositional variables in a
course in first-degree logic at the University of Cambridge. Maybe the
lecturer studied logic in Germany---I don't know.

   They were clearly different from lower-case letters (written in an
unadorned style) and from "script" letters (written as longhand-style
handwriting), so in this subject there were in effect 3 lower-case
alphabets that could be distinguished.

   "Ordinary" letters (in this context) would probably be regarded as
glyph-variants of italic letters, since that's how they appear in
published work. Script characters are hopefully already proposed, as
there's a lot of a script alphabet already in Unicode (B E F H I L M P R
e g [twice!] l o). I wonder whether Deutsche Schrift letters are glyph
variants of Fraktur (black-letter C H I R Z already are encoded, but no
lower-case examples, assuming "black-letter" = "fraktur" [?]), or are
they ever used together to convey different semantics?
