24 <h2>Convert special characters to HTML</h2>
25 <p>
26 With this tool you are able to encode special characters (chars like '&#225;&#232;&#239;&#252;&#241;' '塗聚文'...)
27 to HTML code. The advantage of using special HTML codes instead of the normal characters is
28 that the HTML codes will be readable by most users, no matter what charset is used.</p>
