On the other hand:

$ php -r 'echo iconv("UTF-8", "US-ASCII//TRANSLIT", \
"-Ȧ-Århus-\x30\xCC\xB8-") . "\n";'
-A-AArhus-0-

So while iconv() does not do Unicode normalization, it can be helpful here
(you can replace “AArhus” unambiguously with the correct alternative
spelling for the city, “Aarhus”, for example).
