What would you like to do?
Handle invalid JS character sequences
* encode to handle invalid UTF
* If Chrome tells you "Could not decode a text frame as UTF-8" when you try sending
* data from nodejs, try using these functions to encode/decode your JSON objects.
* see discussion here:
* see also, for browsers that don't have native JSON:
* Any time you need to send data between client and server (or vice versa), encode before sending,
* and decode upon receiving. This is useful, for example, if you are using for real-time
* client/server communication of data fetched from a third-party service like Twitter, which might
* contain Emoji, or other UTF characters outside the BMP.
function strencode( data ) {
return unescape( encodeURIComponent( JSON.stringify( data ) ) );
function strdecode( data ) {
return JSON.parse( decodeURIComponent( escape ( data ) ) );
