Granted, but the name isn't bad given that.

You've done the reverse with "escape." Escaping only applies to the use of "\" to avoid special treatment of some characters within the string and not to the quotation marks at either end. IOW, we need a name that encompasses both delimiting and escaping.

"Encode" doesn't fit well because it has to do with translating from one representation to another due to (computer) language issues. Furthermore, that term is tied irrevocably with Unicode and human language manipulations, which don't apply here.

Is the problem that we have one function doing two tasks? Separate functions for delimiting and escaping (and their reverses) would alleviate the difficulty of finding suitable names for the conflated operations. That of course means that the separate functions must be efficiently composable.
