How to handle localized characters ans special symbols?

[Kövesdán Gábor]

Hello,

I'm translating the FreeBSD webpage to Hungarian. I haven't done too 
much so far, because I don't have too much spare time, but I'll finish 
this translation. Today, I made a test build. You can see this here:

The most part of it is still in English but there are some translated 
pages. The build succeeded quite good, I've found my mistakes easily and 
managed to build the site, but I have troubles with one of the localized 
characters. This is The o letter with two commas on it. Its standard 
html code is ő, but the sgml parser substitutes it with a Q char. I 
don't see why does it happen and don't know how to fix it. There are two 
more problematic characters, and they are ® and ™. They are 
also substituted in a wrong way. See:

You can notice the Z character with a ˇ sign after the word Pentium and 
a " after Athlon.
How could I correctly display these characters? Please tell me what to 
do so that we have a nice Hungarian webpage. :)

(I use Firefox and it selects the ISO-8859-2 Central European encoding 
automatically.)

Thanks in advance,
