See https://www.icao.int/publications/documents/9303_p3_cons_en.pdf from
PDF page 32 / in-document page number 24 onwards.

FWIW, it's worse than what the spec says: Even though the spec allows A for
Ä and O for Ö, Finnish passports do the German-style AE and OE even though
it doesn't really match the preferences of either Finnish-language or
Swedish-language name holders. I imagine that changing what Finland does
for passports could be messy as people's ICAO names would change.
