Ah ok, gracias por la respuesta.

I realise that what I wrote is pointless and I tried to correct an error where there was none, sorry.

Can't find this quote from Che, do you have a link?
Or is it an interpretation of what he said?

¿De donde sacaste la información que "Che" llevaría tilde? Busqué por todas partes y la forma correcta es "Che", sin tilde.

All words have an accent, but not all have an accent mark (tílde).

For example "cangrejo" has an accent in "gre" syllable, but if you write it as "cangréjo" it would be wrong.

Another word like "publicación" has an accent in "ción" syllable and, as you can see, it is written with a tilde.
