    Please don't. "a^e" is <U+0061, U+0364>.

    And ä and æ are "the same", likewise are ö, œ, and ø "the same"
    (in some sense, but not in general). Some (in Denmark and Norway,
    no-where else) even consider aa and å (and <a, small o above>) to
    be "the same" (but not quite, especially when spelling names...).

    Still they are definitely different enough to be considered
    othographic differences, not font differences. Likewise for
    your examples. As for collation, and searches that are advanced
    enough to make use of collation keys, the collation tables
    *can* be tailored so that these variants, within each "equivalence"
    (in some sense) group, have the same level 1 weights (which is
    appropriate for scandinavian and german uses), but different
    level 2 weights (as is appropriate, since this difference is
    (usually) more significant than case distinctions).
