Hi Tomas! Estupendo! Muchas gracias! Really it does work! See http://koha.doxos.eu: 8080/ The succession (collation) of all letters is determined by the order in the list # basic character set lowercase {0-9}aábcčdďeéěfghiíjklmnňoópqrřsštťuúůvwxyýzž uppercase {0-9}AÁBCČDĎEÉĚFGHIÍJKLMNŇOÓPQRŘSŠTŤUÚŮVWXYÝZŽ stored in active sort-string-utf.chr file. The accented letters must not be included in others maps or equivalence statements. How simple, but how difficult to discover it! I would like to express my thanks to all who helped me.

Then I ran koha-rebuild -zebra -a -v -f. It caused the accented letters are assumed to be all the same "e" and the accent is ignored in collation." That's correct. Mapping all variants of e+diacritics means they all "weight" the same (as e) in an ordering. " But grammatically correct is, that the "e" precedes "é", "ě",..... How can I control this succession?" Take the 'es' example (zebradb/lang_defs/es/sort-string-utf.chr) and look for the lines: lowercase {0-9}{a-y}zæøå uppercase {0-9}{A-Y}ZÆØÅ ^^^^^^^^^^ those are the lines you need to adjust. To accomplish your goal you should remove from the mappings those letters with diacritics you want to give a different sorting order (i.e. make them not weight the same as 'e'). The next step is putting them in the lowercase and uppercase lines.in (http://lines.in) the (increasing) order.
