Uint8Array在Javascript中字符串 [英] Uint8Array to string in Javascript

问题描述

我有一些UTF-8编码数据存在于Javascript中的一系列Uint8Array元素中。有没有一种有效的方法将这些解码为常规的javascript字符串（我相信Javascript使用16位Unicode）？我不希望当时添加一个字符，因为字符串concaternation将变为CPU密集型。

I have some UTF-8 encoded data living in a range of Uint8Array elements in Javascript. Is there an efficient way to decode these out to a regular javascript string (I believe Javascript uses 16 bit Unicode)? I dont want to add one character at the time as the string concaternation would become to CPU intensive.

推荐答案

TextEncoder 和 TextDecoder 编码标准的c $ c>，由 stringencoding库，在字符串和ArrayBuffers之间进行转换：

TextEncoder and TextDecoder from the Encoding standard, which is polyfilled by the stringencoding library, converts between strings and ArrayBuffers:

var uint8array = new TextEncoder("utf-8").encode("¢");
var string = new TextDecoder("utf-8").decode(uint8array);
