textEncoder.encodeInto(src, dest)
src<string> 要编码的文本。dest<Uint8Array> 用于存放编码结果的数组。- 返回:<Object>
UTF-8 会将 src 字符串编码到 dest Uint8Array 中,并返回一个包含已读取的 Unicode 代码单元和已写入的 UTF-8 字节的对象。
【UTF-8 encodes the src string to the dest Uint8Array and returns an object
containing the read Unicode code units and written UTF-8 bytes.】
const encoder = new TextEncoder();
const src = 'this is some data';
const dest = new Uint8Array(10);
const { read, written } = encoder.encodeInto(src, dest);
