That it definitely a concern, as someone could conceivably change the Bob section heading to Robert. Or add his surname.

Thanks for the tip about anchor templates, I didn't know about using the id attribute to make an anchor - I knew you couldn't do it using  and never bothered looking into it.
 * More info for anyone else interested: Help:Link#Manual_anchors @meta

To use one, you can add  immediately under the ==Bob== heading, and set the redirect to Characters in X#section-bob]]. Then the heading could be changed but the redirect will still work as long as the id stays the same.

As Mgb2 mentioned, it may be worth using Template:Anchor to allow for.

(I used as the example rather than  because it's valid, short, and works as an initial for section, even though it really means strikethrough. It's deprecated, but I doubt Wikia will ever disallow the tag.)
