Thanks a lot. Passing t for the second argument to replace-match
gives me what I want.

I was just surprised that "=E4" and "=F6" gave me lowercase umlaut-a
and umlaut-o as desired. But replacing "=FC" with umlaut-u did not
work.

But then I would expect that "=E4" (umlaut-a) and "=F6" (umlaut-o)
should give rise to a case conversion, too. Or am I once again
missing something?

The code is supposed to handle various conversions for umlauts:
"7 bit", iso-latin, TeX, german LaTeX, html, mime, etc.
