Is there any way to specify charset in Javascript's encodeURI() or encodeURIComponent()? E.g.:

encodeURIComponent("例子", "UTF-8") outputs %E4%BE%8B%E5%AD%90

encodeURIComponent("例子", "GBK") outputs %C0%FD%D7%D3

• No, these functions are UTF-8 only. What are you trying to acplish? – Christoph Commented Jun 22, 2013 at 10:24
• @Christoph, it's for a dictionary lookup script that dynamically generates links to UTF-8 and GBK pages based on user input data. Is there any functions that can do GBK encoding? – optimizitor Commented Jun 25, 2013 at 16:41

My solution is to used a npm package urlencode and browserify.

Write in urlencode.js:

var urlencode = require("urlencode");
module.exports = function (s) { return urlencode(s, "gbk"); }

browserify urlencode.js --s encode > bundle.js

And in bundle.js, a function called encode is declared.

Based on the earlier edit of this question before you revised it, it seems like you're trying to access various Baidu Baike based on different search terms you submit. My answer is not relevant to your new JS question, but the simple solution to your old problem (and would obviate the need for a JS solution) is to specify the character encoding in the Baidu Baike URL: &enc=. All the following resolve correctly:

• http://baike.baidu./search/word?word=例子&pic=1&sug=1&enc=utf8
• http://baike.baidu./search/word?word=%E4%BE%8B%E5%AD%90&pic=1&sug=1&enc=utf8
• http://baike.baidu./search/word?word=%C0%FD%D7%D3&pic=1&sug=1&enc=GBK

const _encodeURIComponent = (x) =>
    x   
        .split('')
        .map((y) => {
            if (!RegExp(/^[\x00-\x7F]*$/).test(y)) {
                return iconv
                    .encode(y, encoding)
                    .reduce((a, b) => a + '%' + b.toString(16), '') 
                    .toUpperCase();
            } else {
                return y;
            }   
        })  
        .join('');

Replace encoding with desired encoding
