U+00FC being the codepoint of ü. Yes, it is possible, with the right
conditionals. But I thought we were talking about getting it to work
when native Unicode is not enabled. I don't see the need to setting an
active definition when native Unicode support is enabled, either for
writing to auxiliary files or for the final output. When native
Unicode is used, the character would just be written out as-is, read
in as the Unicode character and the corresponding glyph from the
Unicode font would be typeset.
