Support for ANY_CHAR in regular dix files?

[unhammer]

Then we could have bidix entries like <e><i><w/><s n="guess"/></i></e>.

This would require changes to the compiler to allow it, and presumably trim and compose, perhaps also fst_processor?

[mr-martian]

Trim already supports it, compose uses the same equality check as trim, so it should support it too. The compiler just needs lines 420 and 424 changed so it's not checking for is_separable, so it's really just fst_processor that needs non-trivial work.
