Hello,

The strings in the structural specification are in UCS (see Section 2), and the IRIs are just like in the respective specs. Hence,
it seems to me that the structural specification is unambiguous regarding this point.

Now it is true that we don't specify how to encode documents containing an ontology written in functional-style syntax. We could add
a sentence that people SHOULD use UTF-8 for that purpose. If everyone agrees, we can call this an editorial change and I can just do
it.

Regards,

	Boris
