BI-DIRECTIONAL TEXT
Arabic and Hebrew text require bi-directional text support to be displayed correctly, this means that logical
strings should be converted before their visual presentation, so left-to-right and right-to-left sub-strings
are determined and reshuffled. In fvwm this is done automatically in window titles, menus, module labels and
other places if the fonts used for displaying the text are of one of the charsets that require bidi
(bi-directional) support. For example, this includes iso8859-6, iso8859-8 and iso10646-1 (unicode), but not
other iso8859-* fonts.

This bi-directional text support is done using the fribidi library compile time option, see INSTALL.fvwm.
