I am working on Ubuntu server 16.04 with PHP 5.6, Apache2.4 and Mysql. I have a joomla site (3.8) in Greek language and I have a weird problem with the downloaded files. Although all of configurations for charset are "utf-8" (apache, php, server locale, joomla language), when I try to download a file with greek filename, because of apache(?) "cuts" the first letter from the file. For example, the uploaded filename is "Κ1234_ΒΓΔ" and the downloaded filename is "1234_ΒΓΔ". Any ideas for this problem/error?
Thanks in advance
