Hi Scott,
This was bought up in the ECN Chatrooms this evening by Marc (frenchelectrician).
Hence my PM to you.
Now it seems that the great majority of symbols under the ASCII system do work in the Chat room (this being off-site software to the Board), although that may have changed since the upgrade, I'm not sure.
BTW, when using a laptop (I have a Dell Inspiron 500m), if wanting to use these characters, you need to have your secondary keypad enabled in the set-up menu (F2 on startup).
Now depending upon the laptop that you have (Mine has a Fn (function) key written in blue on it.
When using non-standard characters, you need to hold down your Fn (or what it is on your laptop)andthe Alt Key, while you type the code, for a particular character.
I hope that this info actually helps someone.
With a standard keyboard you just hold down the Alt key and then release it before you hit Enter, after having entered the code.
