When linux servers (CentOS 5.x) with PHP 5.3 create Moodle 1.9 backup files using ZIP, Hebrew filenames and folder names are saved within the Zip file with ISO-8859-8 encoding. Zip does not support UTF-8.
Extracting a Moodle 1.9 backup zip file results in file names displayed as "?????????.doc"
And restoring them into Moodle 2+ legacy course_files results in file names displayed as "╫¬╫ץ╫¿╫¬_╫פ╫פ╫ע╫פ.doc"
English filenames restore correctly.
I am attaching a Moodle 1.9 backup file for testing
