title: No \p{L} for JavaScript Regex ? Use Unicode in JS regex
body: <p>I nedd to add <code>a-zA-ZáàâäãåçéèêëíìîïñóòôöõúùûüýÿæœÁÀÂÄÃÅÇÉÈÊËÍÌÎÏÑÓÒÔÖÕÚÙÛÜÝŸÆŒ</code> x time but I find this very ugly. So I try <code>\p{L}</code> but it does not working in JavaScript.</p>
  
  <p>Any Idea ?</p>
  
  <p>my actual regex : <code>[a-zA-ZáàâäãåçéèêëíìîïñóòôöõúùûüýÿæœÁÀÂÄÃÅÇÉÈÊËÍÌÎÏÑÓÒÔÖÕÚÙÛÜÝŸÆŒ][a-zA-ZáàâäãåçéèêëíìîïñóòôöõúùûüýÿæœÁÀÂÄÃÅÇÉÈÊËÍÌÎÏÑÓÒÔÖÕÚÙÛÜÝŸÆŒ' ,"-]*[a-zA-ZáàâäãåçéèêëíìîïñóòôöõúùûüýÿæœÁÀÂÄÃÅÇÉÈÊËÍÌÎÏÑÓÒÔÖÕÚÙÛÜÝŸÆŒ'",]+</code> </p>
  
  <p>I want to have a thing like that : <code>[\p{L}][\p{L}' ,"-]*[\p{L}'",]+</code> (or smaller than the actual expression)</p>
