Pydio version is pydio-core-8.2.2.
Debian GNU Linux 9.5.
I made the settings:
file bootstrap_conf.php
setlocale(LC_ALL, “en_US.UTF-8”);
//define(“AJXP_LOCALE”, “en_EN.UTF-8”);
define(“AJXP_LOCALE”, “”);
my locale:
en_US.UTF-8
/etc/apache2/envvars
export LANG=en_US.UTF-8
But still, searching the Cyrillic part of the file name does not work.
