[R] system call removes special characters from text output

[MacQueen, Don]

I can't reproduce this.

On my system, the contents of an executable file named tmp.pl:

#! /opt/local/bin/perl
print "[A/B]\n";

At a shell prompt:

[72]% ./tmp.pl
[A/B]

Inside R:

> system(' ./tmp.pl')
[A/B]

    Hello,
    
    I am writing an R package, and I am using system() to call a perl script.
    The output of the perl script is correct except for "[A/B]" is output as
    "AB". Can someone explain this behavior. I would like to try and fix this.
    many thanks,
