Assuming you're referring to XML, it's here: http://www.w3.org/TR/REC-xml

A character is a character,  how it is encoded is irrelevent.

Re-encoding an XML file doesn't change whether it is well-formed or not
(assuming you update any encoding specifiers in the document itself.)

So if 'a' is allowed in an element name then the representation of 'a'
in the document's encoding is allowed in an element name, whatever that
encoding is.
