I take it that this table describes the encoding of the byte stream:

while waiting for a built-in translation...)

To convert byte values to code points, you need to apply an encoding
algorithm, and that's kind of messy.
(I believe the rest of GNU APL kind of assumes that UTF-8 is the standard
encoding used, which does make things simpler).
I have a suggestion: Make ⎕UCS support a dyadic form where the left-h
Use the quad function ⎕UCS:

I can use lib_file_io to read a sequence of byte values from a file

How do I convert that sequence back to a Unicode string in GNU APL?
I've analysed the problem using Valgrind, and it seems as though this is a
bug in the XML_Loading_Archive class. The only reason you saw it when
enabling the Emacs mode was that the native plugin caused memory layout to
be slightly different. Different enough that it triggered a crash instead

Greetings,
I was afraid of it blowing up the distribution size too. Both files are
needed to get all the keys since some characters are on the top while other
characters are shown on the side of the keys. Perhaps it would be best to
use the pictures I sent to create a file like your keyboard.txt
I'm using a keyboard from Wasd Keyboards. They allow you to upload a file
containing the symbol design when you order. Making an APL keyboard would
be trivial.

Hi Blake,
I have added the files, see SVN 228.
I also added one of the photos (which blew up the GNU APL tar file from a

Back when I coded in APL, there was discussion about the storage of iota.
For example:

All of these can be represented as a simple equations internally rather
than expanding it all out. It would only be expanded when absolutely

Hi Blake,
0x86 is the culprit because the first byte of a non-ASCII UTF8 should be
11xx in binary.
