Picking up on this point (and the one made by Mike) - it's mostly to do
with your editor. The workbench seems to be unicode aware so it really
is passing a two byte representation of ï¿½ into the interpreter.

If I use the simple command line interface running through an xterm
(X.Org 6.8.99.903) which I guess isn't unicode aware then I get 252 with
the same version of IDL:

IDL> print,!version
{ x86 linux unix linux 7.0 Oct 25 2007 32 64}
IDL> print,byte('ï¿½')
252

but with the workbench:

IDL> print,!version
{ x86 linux unix linux 7.0 Oct 25 2007 32 64}
IDL> print,byte('ï¿½')
195 188

I would expect that if you read the character from a file (either as
data or in a .pro file) it depends on the program which wrote the file
and whether your editor was unicode-aware.

In saying all this, I don't understand unicode properly (does anyone?!?)
- I'm just reporting on the fact that it isn't just the IDL interpreter
which is the issue, it's to do with the editor which sends the character
to the interpreter.

This has already been said - I've just rephrased it using more
(unnecessary?) words. I hope it's helpful.

Thanks,

Allan
