Well, I just tried a minute ago. As Dreamweaver does the "&#xxxxx from/to characters translation" very properly, I think I'll stick to it. I have been using it to work on my personal website in PHP and HTML and DW is just good handling pages with different encoding
In case you don't know, Dreamweaver is not bad for basic PHP editing
Now the problem I have is to find a couple good Messenger resouce sites in Chinese
Traditional.
