Description Aharon (Vladimir) Lanin 2014-03-27 01:07:45 PDT

Unicode 6.3 added new directional formatting characters, U+2066 LEFT-TO-RIGHT ISOLATE through U+2069 POP DIRECTIONAL ISOLATE.

Bug 130823 tracks their implementation. But until that is done, they need to be invisible! Currently, they display as rectangles:

It seems to render similar across all browsers: Safari 17.5 Beta, Chrome Canary 125 and Firefox Nightly 127.

Any thoughts?

They are invisible it seems.

Comment 4 Aharon (Vladimir) Lanin 2024-04-28 00:25:25 PDT

The bug is fixed. They render correctly (at least in Chrome 123, checked right now). That is, they are invisible, but bidirectionally isolate what's inside them from what is outside. See attachment.
