Get the real length of a string - by correctly counting astral symbols and ignoring ansi escape codes
String#length erroneously counts astral symbols as two characters.
$ npm install string-length
import stringLength from 'string-length'; '🐴'.length; //=> 2 stringLength('🐴'); //=> 1 stringLength('\u001B[1municorn\u001B[22m'); //=> 7
Whether ANSI escape codes should be counted. They are ignored by default.
