in thread replacing close-single-quote with apostrophe

For completeness, you can also use the literal character in a one-liner as well:

$ echo Itís easy | perl -Cio -pe "s/í/'/g;"
It's easy

Note that the script, such as it is, is enclosed in double-quotes here only to avoid the problem of escaping the single quote within.

    That command is wrong. You want

    perl -CSD -Mutf8 -pe"s/í/'/g;"

    -Cio has no effect in that example, which you can see by removing it.

    $ echo Itís easy | perl -pe"s/í/'/g;" It's easy

    -Ci only has an effect if reading from a file

    $ perl -Cio -pe"s/í/'/g;" <( echo "Itís easy" ) Wide character in print at -e line 1, <> line 1. Itís easy

    This is what you want if reading from a file:

    $ perl -CiO -Mutf8 -pe"s/í/'/g;" <( echo "Itís easy" ) It's easy

    This is what you want if reading from STDIN:

    $ echo "Itís easy" | perl -CIO -Mutf8 -pe"s/í/'/g;" It's easy

    Combining both, you can use

    perl -CiIO -Mutf8 -pe"s/í/'/g;"

    Better:

    perl -CSD -Mutf8 -pe"s/í/'/g;"
