I've added a play-script at: http://www.jsoftware.com/jwiki/UnicodeGettingStarted So now you can look at the classic "superasciis" like this, and see what they represent nowadays as unicode code-points:
cu '~' ~ U+007E 126 nx 129 U+007F 127 U+0080 128 U+0081 129 U+0082 130 ...etc... ... qui comprend 'ç' et ses amis. Which is _not_ what you get with: 127}. a. BTW, playing with this play-script, I hadn't realised how many bizarre APL characters there were! Did they all ever get implemented? @Bill, Thanks for pointing me at the stdlib support for unicode. Some of them look really useful, like toutf8. I'm not sure I'll abandon my own utilities just yet, though.
