Actually, for German, a-umlaut should map to 'ae', not 'a' (and
o-umlaut to 'oe', and u-umlaut to 'ue').  Likewise, 'ß' should map to
'ss'.  So, if you want to recode Goethe's line

  ... daß beide Männer recht haben möchten ...

into US-ASCII, you would need to put out

  ... dass beide Maenner recht haben moechten ...

The alternative, "das beide Manner recht haben mochten" looks very
wrong to me, though I'm not a native (or even a very good) German
speaker, and perhaps tastes have changed.  It's interesting to note,
though, that the '¨' in old or middle high German was (I think)
originally just a tiny 'e' writting above the vowel by the scribe.

This stuff is always harder than you expect.  I don't know the rules
in Finnish for example, but I'm willing to bet that they handle
ASCII-fication completely differently.  And, of course, once you start
transliterating non-Roman characters, the real fun begins.


All the best,


David
