It is possible to specify their UTF-16 representations using \u escapes. > If not, why was that access excluded? It wasn't a priority to add specific syntax for supplementary escapes in ES5 (remember that ES5 has very few syntax extensions in general, and the ones that it has, such as the get/set object literal syntax, are taken unchanged from existing implementation precedent). I hope that such a syntax will be included in Harmony, though, along with more comprehensive Unicode library support. -- David-Sarah Hopwood ⚥ http://davidsarah.livejournal.com _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
