Code below contains a JS function that receives as parameter String €€ (Euro sign).

Code below contains a JS function that receives as parameter String “€€” (Euro sign).
I need to convert each one of these characters to its ASCII-extended integer equivalent (128 with ISO-8859-1).

However, t[0] and t[1] take value “8364” instead of “128”. What am I doing wrong? Please note that if I use UTF-8 instead of ISO-8859-1, they take value 65533 and in the JS debugger (Chrome and IE developer tools) a question mark is displayed instead of € symbol.

Thanks a mil

    var dataLength = data.length;

    for(n=0;n<dataLength;n++)
    t[n]=data[n].charCodeAt(0);
}
d("€€");
</script>

Full story is that I pasted this “€€” from file “output.js”, where these two bytes were written by Java code below, representing integers [128,128]. That is why I need t[0] and t[1] to get value 128.

res.setContentType("application/octet-stream"); 
res.setHeader("Content-Disposition","attachment;filename=output.js;charset=ISO-8859-1");
ServletOutputStream os = res.getOutputStream();
char result[]=encode(req.getParameter("originalScript"));
// result[0] and result[1] have here integer value 128
String result2=new String(result);
// result2 is displayed here as non printable characters (blank)
os.print(result2);
// On output.js "€€" is displayed

    You have to make sure that the file is actually saved as ISO-8859-1, but that is actually not possible as there is no € character in that character set.

    “ISO/IEC 8859-1 is missing […] the euro sign.”

    http://en.wikipedia.org/wiki/ISO/IEC_8859-1

    As you are getting the character code 8364, the file is most likely saved as UTF-8, as that character code corresponds with the unicode character €.
