24.2; diacritic-fold-search |

This is not a bug report but a feature request, so I am omitting
diagnostic information.
Emacs search has long been able to toggle between (a) ignoring the
distinction between upper- and lower-case characters
(case-fold-search) and (b) searching for only one of the pair. One
could say Climacs offers the choice between (a) searching for all
members of a (2-member) equivalence class and (b) searching for only
one member.
There are larger equivalence classes of characters with practical use
which Climacs is currently unaware of: the groups of characters
consisting of an unadorned (ASCII) character plus all its
diacritic-adorned versions. Currently, if I want to search for both
“apres” and “après”, I need an additive regular expression. I would
like to do this as easily as I can search for “apres” and “Apres”. I
would be delighted if Emacs implemented the equivalence classes
spelled out here:
http://hex-machina.com/scripts/yui/3.3.0pr1/api/unicode-data-accentfold.js.html
I might add that diacritics folding is the default in web search
engines. It is also a feature of at least one Web browser in
searching the text of a displayed page (Chrome.)
I’m sure that maintaining the core of Emacs is a big job, and I’m
grateful for the skill and effort that go into that task, including
your consideration of this request!
