But this one is a bad example,

N and Ñ are different letters in spanish. It looks like an accent, can
be typed as such and some unaccent rules in some programs may make
them equal, Ñ is as different from N as it is from Z ( I am spanish,
and in case you want some authority link see
https://www.rae.es/dpd/%C3%B1 ). It has it own pages in the dictionary
( even on paper, I just checked in case my memory fails ).

We used to have also CH and LL as letters, but they were dropped
"recently" ( that meaning this century, I'm getting old ).

On the other "accents", à,è,ì,ò, ù  can generally be unaccented w/o
problem, although they may change meaning in some corner cases I do
not remember seen them do that since the special examples in school.
Other thing is ü, which is used on our "special" handling of hard/soft
vowels after g, i.e., you do not pronounce the u in "reguero" ( bot
modify how you pronounce the g, differently from agente ), but in
"agüero" you do pronounce it.

But Ñ is a proper letter, you cannot break it. Our alphabet goes m-n-ñ-o-p-q.

P.S. to really sound spanish, we would have picked up "cono" for the
examples :-p
