im working on a javascript/nodejs application that needs to talk with a C++ tcp/udp socket. It seems like I get from the old C++ clients an utf16 buffer. I didn't found a solution right now to convert it to a readable string and the other direction seems to be the same problem.
Is there a easy way for this two directions?
Nice greetings

In Node. js, the Buffer. toString() method is used to decode or convert a buffer to a string, according to the specified character encoding type. Converting a buffer to a string is known as encoding, and converting a string to a buffer is known as decoding.
var buf = new Buffer("Simply Easy Learning", "utf-8"); Though "utf8" is the default encoding, you can use any of the following encodings "ascii", "utf8", "utf16le", "ucs2", "base64" or "hex".
Buffers have a toString() method that you can use to convert the buffer to a string. By default, toString() converts the buffer to a string using UTF8 encoding. For example, if you create a buffer from a string using Buffer. from() , the toString() function gives you the original string back.
let binary = Buffer. from(data); //or Buffer. from(data, 'binary') let imgData = new Blob(binary. buffer, { type: 'application/octet-binary' }); let link = URL.
If you have a UTF-16-encoded buffer, you can convert it to a UTF-8 string like this:
let string = buffer.toString('utf16le');
To read these from a stream, it's easiest to use convert to string at the very end:
let chunks = [];
stream.on('data', chunk => chunks.push(chunk))
.on('end', () => {
let buffer = Buffer.concat(chunks);
let string = buffer.toString('utf16le');
...
});
To convert a JS string to UTF-16:
let buffer = Buffer.from(string, 'utf16le')
