Important notes:
the characters not supported by UTF-8 Unicode are the red ones.
Even using the best browser available, there are characters which are not visible; there is also the possibility that instead of the char it's represented a rectangle or a question mark, it depends on the browser used. To see them, you have to install the corrispondent Language Font Pack, if available.
