conventions - Should there be a space after the copyright symbol ©?

To space, or not to space, that is the question:

Whether 'tis nobler in the mind to place the copyright statement in the footer of an application, or somewhere else, is beside the point. What I want to know is: regardless of where one places it, is there a best practice, convention, or standard that states whether or not one should put a space between the copyright symbol © and the year?

I'm not looking for opinions, but I figured I'd give mine. My personal opinion is that my eye is immediately drawn to the "with space" option as a cleaner solution; the "without space" option somehow just doesn't look right to me.

Answer

A poke around Google suggests that most guides on usage of the symbol agree with your intuition. This article emphasizes that you should use a non-breaking space to avoid the symbol and the copyright holder being on two different lines or pages. Their reasoning is as follows:

Must you put a space af­ter the copy­right sym­bol? No, but se­man­ti­cal­ly, it makes good sense. The © di­rect­ly re­places the word copyright, so it should be spaced like any oth­er word.
