Hi Alecto, sorry for the delay, tedster gave a "hoi" but I got sidetracked.
Can't help you with Spanish fonts I am afraid, but I can shed a little light on Chinese fonts, although if anyone has more experience than me please jump in and correct me.
Types of font -
Chinese writing is the same all over China regardless of the spoken dialect. Having said that, there are two main Chinese Character sets,
"Simplified", the official character set of the Chinese Government which goes with the PinYin romanisation, also the official Romanisation system.
"Traditional" or "Big5", the character set used mainly in Hong Kong and Taiwan, and goes with the older Wade Giles romanisation system put together by, surprisingly, a certain Mr Wade and Mr Giles.
Most chinese poeple would be able to read both, but I would suggest consulting with a Chinese translator about which one to use. See below.
Reading Characters -
Microsoft has Chinese Character support for the Office suite, both 97 & 2000. You will find the fonts in the extras folder for 97, and you can set them up in the install for 2000.
Writing Characters -
Ah, this is a completely different kettle of fish.
You need the character fonts installed that come with Chinese Windows. I am sure you can extract them and overinstall on English Windows but I haven't tried, yet to hard. Running English Office under Chinese Windows is interesting enough without playing around with the systems too much.
Having said that, doing a few searches for this missive, I found a good tutorial Here [geocities.com] about installing chinese fonts on Windows with instructions. New to me, you learn something everyday.
However, you then also need to have a special prgram to enter the characters via PinYin. To do this you really need to understand Chinese quite thoroughly. Really the best way would be to get a Chinese translating web designer to translate and put the page together for you.
