copied!<p>You should do some replacements on the text programmatically. Here are some clues:</p> <ul> <li>All Newlines should be converted to <code>"<br>\n"</code> (The \n for better readability of the output).</li> <li>All CRs should be dropped (who uses DOS encoding anyway).</li> <li>All pairs of spaces should be replaced with <code>" &nbsp;"</code></li> <li>Replace "<" with <code>"&lt;"</code></li> <li>Replace "&" with <code>"&amp;"</code></li> <li>All other characters < 128 should be left as they are.</li> <li>All other characters >= 128 should be written as <code>"&#"+((int)myChar)+";"</code>, to make them readable in every encoding.</li> <li>To autodetect your links, you could either use a regex like <code>"http://[^ ]+"</code>, or <code>"www.[^ ]"</code> and convert them like <strong>JB Nizet</strong> said. to <code>"<a href=\""+url+"\">"+url+"</a>"</code>, but only after having done all the other replacements.</li> </ul> <p>The code to do this looks something like this:</p> <pre><code>public static String escape(String s) { StringBuilder builder = new StringBuilder(); boolean previousWasASpace = false; for( char c : s.toCharArray() ) { if( c == ' ' ) { if( previousWasASpace ) { builder.append("&nbsp;"); previousWasASpace = false; continue; } previousWasASpace = true; } else { previousWasASpace = false; } switch(c) { case '<': builder.append("&lt;"); break; case '>': builder.append("&gt;"); break; case '&': builder.append("&amp;"); break; case '"': builder.append("&quot;"); break; case '\n': builder.append("<br>"); break; // We need Tab support here, because we print StackTraces as HTML case '\t': builder.append("&nbsp; &nbsp; &nbsp;"); break; default: if( c < 128 ) { builder.append(c); } else { builder.append("&#").append((int)c).append(";"); } } } return builder.toString(); } </code></pre> <p>However, the link conversion has yet to be added. If someone does it, please update the code.</p>
