有三个%096;分

I have a .html file created be FrontPage. The encoding was automatically set to Windows1252 (I did not pay attention). I did not change it. I can manually edit it to include Chinese characters, without problem. But the Chinese characters in the files are special code, something like: 有三个%096;分 There is not problem to edit them or showing them using FrontPage, or FireFox. But， now, I want to convert them from simplified Chinese characters to traditional ones. There are many tools to convert Chinese chars, but they do not convert &#26377 in html files. Where can I find the mapping table for these kind of coding? Any information would be appreciated. Thanks in advance.
