It is encoded as %:e (the umlaut exists only for a, o and u)

That's true. We have repeatedly discussed this question in our (DIN)
mirror committee to SC2, but have finally decided against taking this
step for a number of reasons, amongst them:
- problems during data entry: how to ensure that the correct diacritic
is chosen in the correct context?
- compatibility: are the letters WITH DIAERESIS the ones with Umlaut or
with trema? Of course, we would then need a "compatibility decomposition"
(to use the Unicode term) of a, o and u WITH DIAERESIS to a, o, u with
umlaut. This would be ideal for us, but offending for all non-German users
- the problem only occurs in some well-defined areas
This is not perfectly satisfactory and emotionally I would prefer a
different solution. Yet: often one has to choose the lesser evil, and my
rational self fully supports our DIN position. There are many ways to
alleviate the problem of, amongst others, ordering, some of which have been
enumerated by Alain.
So much for this.
