Correct, but is "where does it appear" the question we are
primarily interested in, wrt this breakage and its fix?

If gitweb output has some volatile parts that do not depend on the
contents of the Git test repository (e.g. showing contents of
/etc/motd, date/time of when the test was run, or the full pathname
leading to the trash directory), then preparing a tree whose name is
äéìõû and making sure that the properly encoded version of äéìõû
appears anywhere in the output may not be sufficient to validate
that we got the encoding right, as that string may appear in the
parts that are totally unrelated to the contents being shown and not
under our control.  But is that really the case?

Also we may introduce a bug and misspell the attr name and produce
an anchor element with hpef attribute with the properly encoded URL
in it, and your "parse HTML properly" approach would catch it, but
is that the kind of breakage under discussion?  You hinted at new
tests for UTF-8 encoding in the other message in the thread earlier,
and I've been assuming that we were talking about the encoding test,
not a test to catch s/href/hpef/ kind of breakage.
