Which is the most correct to use while putting together an HTML document?
1) Put the character right into the HTML: ©
2) Use the HTML shortcut for it: ©
3) User the HTML character number: ©
I've always thought that it's best to use the "HTML shortcut"... because using the character can cause problems with uploading to servers sometimes (the server's detect a non-standard character and flag the file as BINARY instead of ASCII), and using the character number would assume you're using a specific character set to render the page (when in fact your page may not be).
What is your opinion on this based on experience? Which should be used? WHY?
Is there a standard out there (W3C or Microsoft or something) that states you should use one or the other?
Thanks for your input on this!
