I don't think it's a bug, because ø doesn't have a decomposition in
the Unicode character database:
(get-char-code-property ?ø 'decomposition) => (248)
(i.e. the character "decomposes" into itself). By contrast:
(get-char-code-property ?á 'decomposition) => (97 769)
(i.e. á decomposes into a followed by U+0301 COMBINING ACUTE ACCENT).
So if one wants to support the kind of folding you expected, one would
have to customize char-fold-include to add those additional rules.
