normalized strings in searches, completion, etc.

["Denis Jacquerye" <moyogo gmail com>]

Hi,

I recently opened a bunch of bugs about lack of normalization of
strings in searches. These could probably be generalized carefully to
many string comparisons.
The problem is basically that a user could type with combining
diacritics instead of precomposed characters. Currently there's many
places where this doesn't work as expected.
For example if I search for "école" with <U+0065 LATIN SMALL LETTER E
+ U+0301 COMBINING ACUTE ACCENT>, the string "école" with <U+00E9
LATIN SMALL LETTER E WITH ACUTE> should be a match.
Some languages have keyboard layouts that have some combining diacritics.

I'm sure there are tones of places where this doesn't work and some
where it does. But it should work everywhere someone does a search or
compares strings unless in some specific cases. What's the best way of
tackling the issue?
