As I said, entities can only escape most Org syntax. Verbatim and code
objects are an exception. Here I think we should introduce an escape
mechanism, much like the one used in macro arguments in order to escape
commas.

For example, in a verbatim object, one only needs to escape "=", using
common "\". Obviously, "\=" constructs can be escaped with "\\=" and so
on. Likewise, in code objects, only "~" needs to be escaped.

In any case, I don't think Org syntax should rely on non-ASCII
characters.
