As there are quite big differences in the expected behaviour of the letters
with diacritics/accents/dots/etc. also among languages that are written in
Latin script, could we have a per-language/locale default settings for the
"Diacritic-sensitive" search option?

For languages like English, French, German, etc., the "Diacritic-sensitive"
checkbox should be off by default, since ä, ö, ü, é/ê/è/ë etc. are considered
variations of the "base" letter in these languages (so a/ä, o/ö, etc. are also
collated together in dictionaries).

For languages like Estonian, Finnish, Icelandic, Swedish, Latvian, Hungarian,
Polish, etc., "Diacritic-sensitive" should be on by default, as there the
(native) letters with "diacritics" (ä, å, á, ā, etc.) are considered separate
letters in their own right, and therefore they shouldn't be ignored/merged with
"base" letter during searching, at least not by default. Some accented letters
that occur in loanwords or foreign names might be considered variations of the
base letter also in these languages - but that's no reason to default to
disabling diacritic-sensitivity. The default setting should reflect the most
common usage.

For languages like Lithuanian, it's probably better to also have
"Diacritic-sensitive" on by default: there, e.g. ą is considered independent
letter, while ã/à are considered variants of a (used mainly in dictionaries to
indicate stress/length).
