> "read scripts before you run them" is a good bit of advice.

I always read the script and do also verify they're only using ASCII chars (and if they're not, I check which Unicode shenanigan is ongoing).

For example:

    ... $ file /usr/local/bin/somescript.sh 
    /usr/local/bin/somescript.sh: Bourne-Again shell script, ASCII text executable

FWIW most of the scripts out there are only ever using ASCII chars.
