Hi,
I have always wondered. Why can you not print "£" in ComputerCraft? I know you can, but when you press backspace, it turns into a question mark.
Another question, how can I grab the tKeys table from the Keys API?
Thanks in advance,
_Zircon_
EDIT: Just thought of another question. How do you stop shutting down and rebooting ?

Not sure about the pound sign.
When I try to copy and paste it into a CC computer (Well, CCEmuRedux), it errors with
window:94: Arguments must be the same length
Probably cause it messes with 'term.blit', CC might see it as more than 1 character or something
As for the Keys API, you can find it in the CC Jar file.
(You can obviously see it in-game, but you can't copy that)

Thanks for your quick response!
I guess I will just keep messing around trying to get it to work, and then I will post a solution if I find one!

Just noticed your edit:

You'd override 'os.shutdown()' and 'os.reboot()', like so:
local oldShutdown = os.shutdown
local oldReboot = os.reboot
os.shutdown = function()
--# The new shutdown procedure
end
os.reboot = function()
--# The new reboot procedure
end
EDIT: This stops other programs from shutting down / rebooting the computer. Ctrl+r / Ctrl+s can't be prevented
Almost forgot about this!

Control+S and Control+R cannot be stopped, just so you know. You can stop programs from shutting down the computer, but not players.

They can be overridden as HPWebcamAble said.

Well, the functions can.
But the key combinations cannot be, they are hardcoded through Java.

Hmm. Just remembered that CTRL+S / CTRL+R don't use os.reboot() or os.shutdown() ;(
Now I see what you guys meant :D/>

CC might see it as more than 1 character or something
That's pretty much it, any characters above 126 are generally rendered as question marks, assuming
that code doesn't bomb out and turn them into two-byte unicode symbols.
I find that by way of simply bypassing the window API I can indeed paste symbol 163, £, in (can't type it as not all keyboards have it), but you still end up with a two-byte value. What's interesting is that it renders in the first place!
Manually defining higher characters with string.char() avoids the unicode thing, but still doesn't allow you to render outside of the 32 - 126 character range (probably because Dan's font-cropping system would make many symbols outside of it illegible). There's a number of threads around discussing it -
eg,
eg,
eg - though thus far I haven't noticed Dan acknowledging it, let alone any interest in fixing it. I suspect the current plan of updating LuaJ will sort it out.
