What do I need to know about this? I've been using Araneae text editor and probably on 1/3 of my pages, which I don't remember which ones, I created a new XHTML document but I ended up saving it with a HTML extension.

Are those pages that I created as XHTML document and then saved with HTML extension in UTF-8 encoding, and the ones I created as HTML and just coded in notepad Western (ISO-8859-1)?

I only need my pages in Wester(ISO-8859-1) because I wont be having anything but English and the common symbols on my keyboard.

What should I do? Do I need to find out what encoding all my pages are in and then declare the proper ones? Or should I just leave them undeclared and let the server and/or browser determine it?

The whole website works and looks great running off my computer but could this encoding cause it to not work great running off a server?

I want to write XHTML transitional, but serve it as HTML pages with an HTML extension.

doesn't matter one little bit what extension you use. Apart from if you use any server side processing.

Unicode (UTF-8) will cover all the symbols & characters needed for 8859-1.

So what if my pages are in different encodings? Would it be ok to not declare their encodings since I don't know what they are? I'm sure the notepad ones are Western (ISO-8859-1), but I'm not sure about the ones I coded in the text editor. It may be UTF-8

it won't matter.

Ok awesome. I'm glad I didn't waste days learning all about the encoding then. lol I really need all my time coding my site and learning more as needed.

Thanks a lot.
