Well, if your editor saves files as i.e. UTF-8 but your text is in ISO-xxxx then it would be in conflict :-)
There are in total 4 points where page encoding can be set / changed:
1. file itself;
2. apache config;
3. PHP config;
4. browser itself.
All of these must 'match' to show good output. And ofcourse - your own text must match all of these criteria. It is a real bugger to get all working well - I know from personal experience.
There are tons of articles which cover this matter. Just Google for keyword: utf-8, website, encoding and you will receive enough results to keep you occupied for weeks
I do not know any specific website that explains this in a propper manner.
Regarding choice of editor, it is a personal choice. All editors have more or less same capabilities. In regard to page encoding, simply when editing a file, choose from File > Properties encoding you need. Almost all editor have this option.
I personally use Aptana (on Linux) as I find it not too hungry for resources and has everything I need (from syntax highlight for HTML / PHP / JS / CSS, to Subversion tools which I extendly use).
Cheers,
