Unhappy How to remove decoration characters from GCC output?


Hi,

After quite a few years I tried to program in C using gcc. In older version there were no decoration characters in between error messages. Now I tried it on Kubuntu Gutsy Gibbon. I find that the error messages contain non-ASCII characters in betweem.

When I use gcc to compile within Emacs these characters make it difficult to read the actual error message. How do I remove these decorations from gcc output? If not, is there a way to make Emacs display them properly?

It all depends on your locale. Here is the result of an experiment (bold text is text I typed, non-bold is output):
Code:
$ echo 'int main() { return bar; }' > foo.c
$ LC_ALL=en_US.UTF-8 make foo
cc     foo.c   -o foo
foo.c: In function Ďmainí:
foo.c:1: error: Ďbarí undeclared (first use in this function)
foo.c:1: error: (Each undeclared identifier is reported only once
foo.c:1: error: for each function it appears in.)
make: *** [foo] Error 1
$ LC_ALL=en_US make foo
cc     foo.c   -o foo
foo.c: In function 'main':
foo.c:1: error: 'bar' undeclared (first use in this function)
foo.c:1: error: (Each undeclared identifier is reported only once
foo.c:1: error: for each function it appears in.)
make: *** [foo] Error 1
Notice that in the first, the single quotes are actual unicode quote marks (Ďí). In the second, they are the ASCII straight quotes ('').

As for getting Emacs to display them properly, I canít help you there, though Iím sure itís possible (I am a vi man myself .
