Weird characters displayed in Linux

I was compiling HPL today and I was getting this error, among others:

 error: expected declaration specifiers or â...â before âMPI_Commâ

I have seen this encoding issue in some man pages too and had simply ignored it, but today I thought I've had enough so I looked for a solution. The solution is very simple:

export LC_ALL=C

 The output now is:

error: expected declaration specifiers or '...' before 'MPI_Comm'

Don't forget to add it to your .bashrc file (/home/username/.bashrc) to make the change permanent.
