I agree with Dom86 & geekay, if done correctly, someone SHOULD be able to insert the symbol by holdin "alt+shift" and typing "0169" as they write the HTML (On Mac it's option+G) and not have to use the &169; or whatever. Some browsers will default to read the ascii charset, but it's a really good to have the Doctype there just incase... and it makes it easier just to include the original charactor instead of the ascii equivalent.
I don't understand what the doctype has to do with the original problem about the displaying. Doctype is needed for validating the html.
Doctypes do a lot more than just facilitate validation. They tell the browser how and why to interpret all sorts of things in both the html source and css file and this can make a HUGE difference in how a page renders cross-browser. Without the doctype browsers are free to interpret as they see fit; with the doctype they are forced (in most cases) to interpret according to the guidelines of the doctype.
There are so many reasons to add a doctype to every page. This thread points out another minor one.

createErrorMsg is right. And we get so many posts asking "is the doctype important", "do I really need a doctype", etc that I've flagged this thread so that I can cite it next time the question comes up.
