I see that the documentation suggests that (entity-charset) is supposed to return a symbol. However, it nearly always returns a string. In particular, it appears to me that it returns a symbol only when it returns its default, 'us-ascii.
I feel compelled to repair this, but there are two ways to fix it: 1) make it match the docs and always return a symbol, or 2) change the docs and the default to return a string. It looks to me like #2 will break (less) code, though it's certainly possible that people depend on the default value's being a string. Opinions? In my tree, I've added contract checks on the structure exports and changed the documentation and default to always return a string. If people like this, I can just submit it as a pull request.
