I'm really surprised! Would you please quote chapter and verse?

On a separate note, "a with acute" was just an example. For a better
example, that is also real life, consider the Lithuanian letter LATIN
SMALL LETTER A WITH OGONEK AND ACUTE. It's not representable with one
character in either Unicode or ISO/IEC 10646. You would need a character
sequence, like U+0105 U+0301. Here, U+0301 has "Inherited" as its
script.
