Perldoc shows single quotes as garbage characters

[ATC]

When using 'perldoc', code examples are garbled beyond practical use by any occurances of special characters like single quotes.

This is usually caused by broken terminal settings, but there's a very simple workaround. Simply tell perldoc to display text using pod2text instead of pod2man and nroff.

perldoc -t

Or more conveniently: Edit your ~/.bash_profile and add the following:
export PERLDOC="-t"
