I'm still baffled
Unicode is an encoding, it maps abstract characters and symbols to
hexadecimal values, nothing more (actually, there is a lot of ancillary
stuff as well, but we'll ignore that, pro tem)
most known characters and quite a lot of technical symbols can be mapped
to hexadecimal values using Unicode
the technical symbols include every published APL symbol ever used in
any way
it also includes just about every mathematical symbol the American
Mathematical Society could think of
so a stream of mathematical symbols could be encoded using Unicode
values, and (if one exists) a semantically equivalent stream of APL
symbols could also be encoded using Unicode values
I'm sure you knew that
Unicode has no functional power, and in particular, it doesn't have
markup, so I should amend that earlier statement to "a _linear_ stream
of mathematical symbols..."
a stream of mathematical symbols, with embedded markup (presumably
ASCII-only), could also be encoded using Unicode values
conversion to a semantically equivalent stream of APL symbols could be
done by hand, or using a programming language[1], but I doubt very much
if a general solution exists
so, yes, some 2-D mathematical expressions could be translated into
executable APL using only Unicode values, which is my present best guess
at what you were asking
and if I've misunderstood you, my apologies
all the best . . . /phil
[1] note that there is no requirement for the programming language to
know anything about Unicode -- Unicode 1.0 has a copyright date (c)
1990, 1991 and at that time (before the introduction of w_char) some
people were already using unsigned ints to store Unicode values
