Source: libtext-bidi-perl Version: 2.15-1 Severity: wishlist libtext-bidi-perl’s upstream includes a file, misc/bidi, that can be used as a urxvt extension. (The extension filters terminal output through fribidi to display RTL text correctly.) It would be great if misc/bidi could be installed through apt.
It looks like Debian puts system extensions for urxvt in /usr/lib/$DEB_HOST_MULTIARCH/urxvt/perl.
