Changes: * Charsets other than UTF-8 supported, Latin1 and Latin2 only now (Wikipedia uses only Latin1 and UTF8), but it requires to edit exactly 3 lines to add another encoding (1 line to add new type to encoding_t, another to say what is its name, and third to say what should be LaTeX header for it). If no or unknown encoding is passed, texvc assumes it is UTF-8. At least it is right if it's some ASCII-only string. * texvc_cgi.phtml now generates right HTTP Content-Type headers with encoding * both OutputPage.php and texvc_cgi.phtml pass encoding to texvc * (not really related to texvc, but also included) <pre> changed back to old behaviour

Now the only important unresolved things are CJK support and PNG transparency. But I think we can live without them for now.

Oh, and texvc should allow more characters in \mbox{}, not only letters and those with 8th bit set.
