  1. POHow do I correctly decode unicode parameters passed to a servlet
    text
    copied!<p>Suppose I have:</p> <pre><code>&lt;a href="http://www.yahoo.com/" target="_yahoo" title="Yahoo!&amp;#8482;" onclick="return gateway(this);"&gt;Yahoo!&lt;/a&gt; &lt;script type="text/javascript"&gt; function gateway(lnk) { window.open(SERVLET + '?external_link=' + encodeURIComponent(lnk.href) + '&amp;external_target=' + encodeURIComponent(lnk.target) + '&amp;external_title=' + encodeURIComponent(lnk.title)); return false; } &lt;/script&gt; </code></pre> <p>I have confirmed <code>external_title</code> gets encoded as <code>Yahoo!%E2%84%A2</code> and passed to <code>SERVLET</code>. If in <code>SERVLET</code> I do:</p> <pre><code>Writer writer = response.getWriter(); writer.write(request.getParameter("external_title")); </code></pre> <p>I get <em>Yahoo!â„¢</em> in the browser. If I manually switch the browser character encoding to UTF-8, it changes to <em>Yahoo!<sup>TM</sup></em> (which is what I want).</p> <p>So I figured the encoding I was sending to the browser was wrong (it was <code>Content-type: text/html; charset=ISO-8859-1</code>). I changed <code>SERVLET</code> to:</p> <pre><code>response.setContentType("text/html; charset=utf-8"); Writer writer = response.getWriter(); writer.write(request.getParameter("external_title")); </code></pre> <p>Now the browser character encoding is UTF-8, but it outputs <em>Yahoo!â¢</em> and I can't get the browser to render the correct character at all.</p> <p>My question is: is there some combination of <code>Content-type</code> and/or <code>new String(request.getParameter("external_title").getBytes(), "UTF-8");</code> and/or something else that will result in <em>Yahoo!<sup>TM</sup></em> appearing in the <code>SERVLET</code> output?</p>
