如何在utf-16中编码JavaScript字符串? [英] How do I encode a JavaScript string in utf-16?

问题描述

在Python 3中，我可以这样做:

In Python 3, I can do this:

>>> "€13,56".encode('utf-16')
b'\xff\xfe\xac 1\x003\x00,\x005\x006\x00'

输入是一个(unicode)字符串，而输出是该字符串的原始字节序列，该字符串以utf-16编码.

The input is a (unicode) string, while the output is a sequence of raw bytes of that string encoded in utf-16.

如何在JavaScript中做同样的事情-从一个(unicode)字符串转换为以utf-16编码的那个字符串的原始字节序列(也许是 Uint8Array ?)?/p>

How can I do the same in JavaScript - go from a (unicode) string, to a sequence of raw bytes (perhaps as a Uint8Array?) of that string encoded in utf-16?

推荐答案

您想要这个吗?

function strEncodeUTF16(str) {
  var buf = new ArrayBuffer(str.length*2);
  var bufView = new Uint16Array(buf);
  for (var i=0, strLen=str.length; i < strLen; i++) {
    bufView[i] = str.charCodeAt(i);
  }
  return bufView;
}

var arr = strEncodeUTF16('€13,56');
