Is it possible that there is some messup in the APL UP TACK and DOWN
TACK symbols? They all seem to be the wrong way round:
U+22A5 UP TACK looks as one would expect like this:
|
|
|
|
-------
However, U+2351 APL FUNCTIONAL SYMBOL UP TACK OVERBAR looks to my surprise
like
-------
-------
|
|
|

in Unicode 2.0. It seems that all of
U+234A APL FUNCTIONAL SYMBOL DOWN TACK UNDERBAR
U+234E APL FUNCTIONAL SYMBOL DOWN TACK JOT
U+2351 APL FUNCTIONAL SYMBOL UP TACK OVERBAR
U+2355 APL FUNCTIONAL SYMBOL UP TACK JOT
U+2361 APL FUNCTIONAL SYMBOL UP TACK DIAERESIS
are named the wrong way round and that UP/DOWN should be exchanged.
In general, I have the feeling that APL is a rather dark area of Unicode
2.0 that was perhaps not too carefully scrutinized. Are there any
official conversion tables between Unicode and and historic APL fonts or
character sets available?
