Equivalent in the following sense: if the text includes ñ (these are 2 separate characters, they are just combined for display), then searching for either n or ñ (a single character in both cases) should find that 2-character sequence. This follows the "canonical equivalence", described in more detail here: http://unicode.org/reports/tr10/#Canonical_Equivalence > If my understanding is correct now (the feature is some Unicode thing > and not about how characters are used by people) I insist on defaulting > to off, unless we renounce to make Emacs amenable to those who use a > text editor for natural languages. It _is_ about how characters are used, see above. And you don't need to insist, you can just turn it off in your sessions. You have heard at least 2 people whose opinions are to the contrary, for various valid reasons.
