compilation output has many nonprintable characters, what shall I do?

[patiobarbecue]

Dear there,

I use M-x compile, followed by make -k, and the output always contains many
nonprintable characters like this:

decomp.cpp:460: error: ‘setw’ was not declared in this scope
decomp.cpp:460: error: ‘setprecision’ was not declared in this scope

Any help would be appreciated, thanks!

Make it display in UTF-8 encoding. Then you would see ‘setw’  
instead.

[patiobarbecue]

in the output window where the nonprintable characters are, I issued the
command:
C-x RETURN f UTF-8 RETURN
and emacs shows no match. I am a little bit confused. Am I doing the right
thing to "make it display in UTF-8 encoding"? Thanks for reply.

It's "utf-8", in lower-case.

Patio,

Try using  "LOCALE=C make -k"
without the quotes as your build command.
GCC tries to use smartquotes if locale supports it.
However Emacs tends to get confused with them.

The above command tells GCC that the shell (emacs)
doesn't support smart quotes.


HTH,

Opps, that should be LANG or LANGUAGE, not LOCALE.

This works like a charm, thanks. For my GNU Emacs 22.1.1 (i486-pc-linux-gnu,
GTK+ Version 2.12.9) on Ubuntu 8.04, Miller's solution "LANG=C" solves the
problem perfectly. Thanks!

Assuming this is Emacs 22, Emacs does not get confused by Unicode
characters like that.  More probably, the OP's setup of Emacs is
somehow in contradiction with the shell's locale, because Emacs
generally uses the same environment variables as GCC to decide whether
GCC will use UTF-8 in its output.

Emacs certainly does, unless you interfere with its default setup of
locale-related issues.
