Hi Markus,
Are you using UTF-8? It's the only character set we support. It's also
possible that your font does not contain all the characters you need,
but if that's the case at least something should show up. I would
suggest compiling a list of chinese characters you're likely going to
need, and simply skip the rest. You're going to have to either enter
them one by one the text box reserved for single characters or use
Firebug or something similar to modify the value attribute of one of
the checkboxes to match the unicode range you want. Or if you're
running Linux or OS X, you can also install a local copy of the
generator and mofdify it to your heart's content.
You may also wish to disable kerning as it might save at least some
space.
Overall I think it's going to be a bad idea to use the font if you
can't get it down to a more manageable size. Even if your server
supports gzipping (which means that the transferred data probably ends
up being somewhere around 500KB), it can take a while for a browser to
go through the 5MB of data once it's been uncompressed.
By the way do you have an example?
Simo
