| // Demo: http://mothereff.in/js-escapes | |
| function unicodeEscape(str) { | |
| return str.replace(/[\s\S]/g, function(character) { | |
| var escape = character.charCodeAt().toString(16), | |
| longhand = escape.length > 2; | |
| return '\\' + (longhand ? 'u' : 'x') + ('0000' + escape).slice(longhand ? -4 : -2); | |
