[Koha] Koha 3.20.3 UTF-8 Problems

[Abdulsalam Yousef]

Hello All,

Koha 3.20.3 suffers from UTF-8 Problems in some pages such as, When trying
to edit help in
        Arabic interface
        it shows garbage like this:

        ٠رحباً بك٠٠ي ÙƒÙiˆÙ‡Ø§

        إذا كانت هذه هي ال٠رة الأولى
الأخرى ال٠وجودة ٠ي الإدارة.

        Although it shows help good in Arabic when reading help.
Also when trying to import borrowers form tools > Import patrons

Default values like (Salutation:, Surname, ...etc) looks like (تحية:)
in Arabic interface, Although it's ok in Arabic interface columns.def file,
Also the same thing when trying to build new Guided reports from Guided
reports wizard.

Thanks
