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-hand side specifies the encoding to use. I.e: *'UTF-8' ⎕UCS 99 100 101 102* Handling multiple encodings is easily done through the *libiconv* library. I worked on it when I made some improvements to its Common Lisp integration. It's quite simple to use. Regards, Elias On 28 April 2014 12:49, David B.
