utf-8 Chinese string

[Sloaix]

hi man.
I met a question when i used Gzip to decompress String.When I decompress a utf-8 Chinese String.it will be wrong.
Because i use ajax to exchange data.And the xhr.responseText is gziped by server.
so i need to decompress the data on browser.
can you give me some advice?
thx : )

Use https://github.com/inexorabletash/text-encoding for decoding UTF-8 characters

//unint8Arr转char
function Uint8ArrToChar(array) {
	var out, i, len, c;
	var char2, char3;

	out = "";
	len = array.length;
	i = 0;
	while (i < len) {
		c = array[i++];
		switch (c >> 4) {
			case 0:
			case 1:
			case 2:
			case 3:
			case 4:
			case 5:
			case 6:
			case 7:
				// 0xxxxxxx
				out += String.fromCharCode(c);
				break;
			case 12:
			case 13:
				// 110x xxxx 10xx xxxx
				char2 = array[i++];
				out += String.fromCharCode(((c & 0x1F) << 6) | (char2 & 0x3F));
				break;
			case 14:
				// 1110 xxxx 10xx xxxx 10xx xxxx
				char2 = array[i++];
				char3 = array[i++];
				out += String.fromCharCode(((c & 0x0F) << 12) |
					((char2 & 0x3F) << 6) |
					((char3 & 0x3F) << 0));

	return out;
}

//char转uint8Arr
function charToUint8Arr (str) {
	var code;
	var utf = [];
	for (var i = 0; i < str.length; i++) {
		code = str.charCodeAt(i); //返回每个字符的Unicode 编码
		if (code < 0x0080) { //ascII
			utf.push(code); //返回指定位置的字符
		} else if (code < 0x0800) {
			utf.push(0xC0 | ((code >> 6) & 0x1F));
			utf.push(0x80 | ((code >> 0) & 0x3F));
		} else if (code < 0x10000) { //中文
			utf.push(0xE0 | ((code >> 12) & 0x0F));
			utf.push(0x80 | ((code >> 6) & 0x3F));

			throw "不是UCS-2字符集"
