encoding issue

Hello
Thank you for the module
in admin/settings/date-time (Date and time)
and views
Hijri date appear like this صباحاً
I fix that by change the encoding to UTF-8 and re-write the months and days
so please re-place
calendar_systems\calendar\v1\calendarSystems\arabic.class.inc.php
with the fixed file (attatched)
