This gem provide bidirectional text support for Prawn. It uses Unicode Bidirectional Algorithm for displaying text from TwitterCldr::Shared::Bidi and connect arabic letters using Arabic Letter Connector. Prawn patching is minimal, we patch only Prawn::Text::Formatted::Box#original_text.
Ruby and Rails internally provide unicode string normalization and store normalized letters inside. But Prawn don't connect arabic glyphs back and don't suport mixet LTR and RTL string. This gem add this suport.
This gem use same code as Arabic Letter Connector by @staii and therefore based on Arabic-Prawn by Dynamix Solutions (Ahmed Nasser).

Or install it yourself as:
$ gem install prawn-rtl-support
prawn-rtl-support provide method Prawn::Rtl::Connector#fix_rtl(string) which reverse string and connect arabic letters.
Prawn patching is minimal, we patch only Prawn::Text::Formatted::Box#original_text.
