  如果是jQuery：

  jQuery('#qrcode2').qrcode({

  text: utf16to8("中文支持")

  });

  function utf16to8(str){

  var out,i,len,c;

  out="";

  len=str.length;

  for(i=0;i<len;i++){

  c=str.charCodeAt(i);

  if((c>=0x0001) && (c<=0x007F)){

  out+=str.charAt(i);

  }else if(c>0x07ff){

  out += String.fromCharCode(0xE0 | ((c >> 12) & 0x0F));    

        out += String.fromCharCode(0x80 | ((c >>  6) & 0x3F));    

        out += String.fromCharCode(0x80 | ((c >>  0) & 0x3F));   

  }else{

  out += String.fromCharCode(0xC0 | ((c >>  6) & 0x1F));    

     out += String.fromCharCode(0x80 | ((c >>  0) & 0x3F));

  }

  }

  return out;

  };

  如果是前两种zxing和qrcode

  hashMap.put(EncodeHintType.CHARACTER_SET, "utf-8");
  

  指定编码方式为UTF-8即可
