Description paxed 2018-02-22 13:09:54 UTC
For some languages, the default collate rule set in kohastructure.sql, utf8_unicode_ci, doesn't work correctly.

For example, Finnish alphabet expects the alphabet to sort abc...xyzåäö, but the unicode_ci rule doesn't handle the åäö right. Instead, we need to use the swedish_ci rule.

It would be nice to be able to define the default collate rule during install.

Problem can be seen for example when you go catalogue a new record and have frameworks starting with 'ä' or 'ö', those will sort incorrectly.

On the database, you can test this with:

insert into biblio_framework (frameworkcode, frameworktext) values ('TEST', 'Äänikirja');

-- Note where the 'Äänikirja' is located
select * from biblio_framework order by frameworktext collate utf8_unicode_ci;

-- And then the correct order, with 'Äänikirja' last:
select * from biblio_framework order by frameworktext collate utf8_swedish_ci;
