The frawk implementation (not quite POSIX, but extremely fast) and my GoAWK implementation both have an "-i csv" option that puts it in "input mode CSV". More here: https://benhoyt.com/writings/goawk-csv/

  $ cat quoted.csv
  "Smith, Bob",42
  $ awk -F, '{ print $1 }' quoted.csv
  "Smith        # you want to print the first field: Smith, Bob
  $ goawk -i csv '{ print $1 }' quoted.csv
  Smith, Bob    # that's better!
