        const output = stdout.match(/"dst":"(.*)"/)[1];
        log('xxx=>', output, typeof output);    // xxx=>, \u6536\u5230, string
        const output1 = '\u6536\u5230';
        log('xxx=>', output1, typeof output1); // xxx=>, 收到, string

\ characters have special meaning (they are escape sequences) in string literals in JS source code.

They don't have special meaning in external input.

I guess the question becomes “how do you convert the string to JS escape sequences”?
