I don't understand. How gets 'ö' mapped to 'o'? It is not NFC, but
it can't be transliteration either, can it? I thought that the idea
of transliteration is to map non-ASCII characters to ASCII strings
unambiguously, so I could imagine that 'Bögen' gets mapped to
'B_oe_gen' or something similar. Stripping off the umlaut dots from
the 'ö' character to convert 'Bögen' to 'Bogen' can never be the right
solution.

OK. But it still doesn't explain why 'ö' gets mapped to 'o'.

I have no opinion here. IMHO, it should work with or without
`--no-transliterate0file-names`. What I currently see is a strange
Texinfo warning message that implies that I can't use `@anchor{Bogen}`
and `@anchor{Bögen}` at the same time. There are many languages where
you have different words – probably also in French – that become
identical if you strip off the diacritics.
