There are currently none.  Context separators are used to separate names
in fully or partially qualified names, like in "Foo<sep>Bar".  So this
separator string should be one put in tags scope by ctags.

However, some language indeed don't put any, and generate unqualified
scopes -- as does the ASCIIDoc one.

We don't currently have anything to specify "no separator", but we
probably could go for some ASCII control sequence, like ETX (\x04, End
of Text), EOT (\04, End of Transmission) or pretty much anything that's
not printable or blank.

BTW as we discussed on IRC, we can't really return "" (empty string) or
NULL because it would somewhat break the plugin API (and it would
actually break plugin geanygendoc).

Do you expect me to know every language? :)
Though, in real programming languages there generally are rules on what
an identifier can be, so most languages will allow a context separator.
 And even, most languages will have one, as part of the syntax to access
nested units, like "." and "->" in C, ".", "::" and "->" in C++, "::"
and "->" in PHP, "." in Python, etc.

So, as we discussed on IRC I suggest we pick an ASCII control character
(or sequence) and return this for languages that should allow anything
in tag names.
