• Set the 'rightleft' option, unless 'termbidi' is set.
• Set the 'arabicshape' option, unless 'termbidi' is set.
• Set the 'keymap' option to "arabic"; in Insert mode CTRL-^ toggles between typing English and Arabic key mapping.
• Set the 'delcombine' option Note that 'encoding' must be "utf-8" for working with Arabic text.

Resetting this option will:

• Reset the 'rightleft' option.
• Disable the use of 'keymap' (without changing its value). Note that 'arabicshape' and 'delcombine' are not reset (it is a global option). NOTE: This option is reset when 'compatible' is set. Also see arabic.txt.
