When pfg-server servers a static file in HTTP mode, it is output as is, so
specifying charset="iso-8859-1" could be wrong.
Note: the a charset can be specified with a meta tag in HTML files,
e.g. for files in UTF-8:
<meta http-equiv="Content-type" content="text/html;charset=UTF-8">
pgf-server can now act as a standalone HTTP server. To activate this mode,
start it with
pfg-server http
to use the default port number (41296), or give an explicit port number, e.g.,
pgf-server http 8080
The HTTP server serves PGF files in the same way as the old FastCGI interface.
In addition, it also serves static files. The document root for static files
is the www subdirectory of the current directory where pgf-server is started.
In spite of these addition, backwards compatibility is maintaned. The old
FastCGI interface continues to work as before. (It is activated when
pgf-server is started without arguments.)
