We have a website, where some pictures name using unicode, e.g. wildkräuter2_big.jpg.
Problem is - when anybody trying to access it - Apache 2.4 returns a 404 error:
$ curl -r 0-99 http://domain.tld/wp-content/uploads/2014/11/wildkräuter2_big.jpg
in Apache's log:
40...168 - - [30/Jun/2016:13:27:36 +0000] "GET /wp-content/uploads/2014/11/wildkr%C3%A4uter2_big.jpg HTTP/1.0" 404 22295 "-" "curl/7.35.0"`
%C3%A4 here - is an ä, as Deutsch - Unicode Tabelle says.
If execute GET with %C3%A4 - it will not work.
If execute GET with an a%CC%88 - it will work:
$ curl -r 0-99 http://domain.tld/wp-content/uploads/2014/11/wildkra%CC%88uter2_big.jpg

I'm not sure - from where I got an a%CC%88 code - but it works.
So, two "same" URLs:
http://domain.tld/wp-content/uploads/2014/11/wildkra%CC%88uter2_big.jpg - this works
http://domain.tld/wp-content/uploads/2014/11/wildkr%C3%A4uter2_big.jpg - this does not work.
Both a%CC%88 and %C3%A4 means same - an ä letter.
This site was migrated from other agency and we haven't information about its setup.
Our current server works under Ubuntu 14.04, with LANG=de (apache2 was restarted after LANG was changed, but not whole Linux server) as locale and ext4 filesystem:
