Hello all,
rxvt-unicode can't display ل and ا correctly as discussed in
https://github.com/mkamensky/Text-Bidi/issues/10
due to special_encode in rxvtperl.xs
https://github.com/exg/rxvt-unicode/commit/91e9e34407c92474822d06afb5c56419f576a664#diff-bbd4b6a86bc65b6ac8e79e97afc61499158edb40f7bb404c70637b46d80a7ad2
I think I have an idea why Urxvt can't display ل and ا correctly. each
character takes 2 bytes so normally لا is an array of two chars with the
size of 4 bytes. But لا has it's special Unicode value "U+FEFB" which
takes 3 bytes. So if urxvt can't allocate more than two bytes to each
character and tries to display لا using it's unicode character then it's
safe two assume that's causing the problem. Please see the attached
screenshot.
