Strange characters in ansi-term in emacs

Question

I wrote a c++ program and when I compiled it using g++ in ansi-term, I got some strange characters displayed:

enter image description here

If required, the error was that i hadn't declared the variable n. How can I correct this?

Looks like you're using `gccfilter` or something similar to color your output. Those are terminal escape sequences. — Sean Bright, Jan 16 '13 at 17:51

Ah! Tested this...

 (setq locale-coding-system 'utf-8)
(set-terminal-coding-system 'utf-8-unix)
(set-keyboard-coding-system 'utf-8)
(set-selection-coding-system 'utf-8)
(prefer-coding-system 'utf-8)

and problem solved!!!

Looks like the gcc output contains UTF-8 "smart quotes" and your terminal is not set up to display UTF-8. The simple workaround is to use a locale which does not support smart quotes inside Emacs, which should force gcc to fall back to plain-jane ASCII quotes; a more sophisticated fix would be to fix the terminal mode in the Ansi-Term buffer to display these correctly.

Those are most likely color escape sequences. emacs has a mode for that which you can enable with the ansi-color-for-comint-mode-on function.

@sudeepdino008 - does it do anything? – jtahlborn Jan 16 '13 at 18:36
No.Nothing. I tried it in various ways, nothing happened. No message, nothing. – sudeepdino008 Jan 16 '13 at 18:58
@sudeepdino008 - what happens if you run 'ls --color=tty' in the terminal window? – jtahlborn Jan 16 '13 at 19:11
@sudeepdino008 - also, what is the value of the "TERM" environment variable? – jtahlborn Jan 16 '13 at 19:14
right. so when i do ls --color=tty', i get folders and files listed in different colours. And when i do echo $TERM, i get eterm-color. – sudeepdino008 Jan 16 '13 at 20:24
@sudeepdino008 - so, ansi term color stuff is "working", but somehow the tool you are using is spitting out weird color sequences. what tool specifically are you using which is generating those? – jtahlborn Jan 16 '13 at 21:18
what do you mean by which tools i am using? – sudeepdino008 Jan 17 '13 at 07:46
@sudeepdino008 - what is genarting the color sequences? – jtahlborn Jan 17 '13 at 13:03
