To address first the question you ask in the Subject line, How to
remove accents while conforming to language standards?, but do not ask
in the message body, the answer is: You cant. Well, except in cases
where language standards permit the omission. For example, according to
modern French orthography standards, the circumflex in frache could
and should be dropped (though it is still very common to keep it).

NFD does *not* remove accents. It is decomposition, not destruction. It
decomposes, say, to a followed by a combining ring above. If you
then have your own code removes the combining marks, thats a different
issue, and generally a wrong thing to do.

Should as per which standard or policy? It is gene rally accepted for
Danish to replace by aa if you cannot use . But what might be
the situation, in the year 2013, where you really cannot use ?

There are various language-specific practices. They are not universal.
For example, in Spanish texts, I dont think many people would find it
acceptable to replace by ue, rather than just u, if some evil
powers force you to stick to Ascii characters.
