Android Java UTF-8 HttpClient Problem

Question

I am having weird character encoding issues with a JSON array that is grabbed from a web page. The server is sending back this header:

Content-Type text/javascri

Extract the charset from the response content type field. You can use the following method to do this:

private static String extractCharsetFromContentType(String contentType) {
    if (TextUtils.isEmpty(contentType)) return null;

    Pattern p = Pattern.compile(".*charset=([^\\s^;^,]+)");
    Matcher m = p.matcher(contentType);

    if (m.find()) {
        try {
            return m.group(1);
        } catch (Exception e) {
            return null;
        }
    }

    return null;
}

Then use the extracted charset to create the InputStreamReader:

String charsetName = extractCharsetFromContentType(connection.getContentType());

InputStreamReader inReader = (TextUtils.isEmpty(charsetName) ? new InputStreamReader(inputStream) :
                    new InputStreamReader(inputStream, charsetName));
            BufferedReader reader = new BufferedReader(inReader);
