Hi, I want to convert strings in which the characters with accents
should be converted to the ones without accents.
AFAIK, “ä”, “ö”, and “ü” are not accented characters in any natural
language, but characters of their own (umlauts).
In particular, I know for certain that they are not accented in Germanic
languages. Swedish has been mentioned; I can add my native language,
German, to that list.
In German, they are letters, but they collate as either ae, oe, ue
(rarely) or a, o, u (modern style). Ad dictionary or phone book does not
have an "ö" section in Germany. Example from a German-Latin dictionary,
printed in 1958
Laster -> vitium
Lästerer -> homo maledicus
lasterhaft -> vitiosus
If "ä" would sort as a single letter, "Lästerer" would be the last
entry. If it would sort as "ae", it would be the first entry. Therfore,
in this example it sorts as "a", with "ä" > "a" to resolve a tie only.
