Powerline symbols?

I’ve responded privately to Rebecca and to Debbie Anderson from SAH.

We did make a significant effort to get Powerline and other symbols encoded, comparable to the successful multi-year effort to encode Symbols for Legacy Computing. We encountered additional challenges with this newer proposal, and I was unable to devote time in the first half on 2021 to resolving them, but we will try again.

As you (Mark) discovered, the name originates from the piece of software which first used these characters, called Powerline. It's a plugin for vim, tmux, bash, i3, and several other environments that �adds a fancy status line to the terminal.

 �

The characters have been proposed before, in document L2/19-068R2. The SAH recommended encoding three of them (the branch symbol and the row and column number symbols) but the UTC took no action. I vaguely recall a recommendation (from the SAH?) for the author, Renzhi Li, to contact the "Terminals Working Group" (Doug Ewell, me, and a few other individuals) to work out integrating them into a "round 2" Symbols for Legacy Computing proposal. We were never contacted by the author but we integrated them into a "round 2" proposal anyway, �with the suggestion to use the same code points as were recommended by the SAH.

 �

That "round 2" proposal was brought to the UTC but for some reason was never added to the document register. We had an hour-long meeting in which the UTC reviewed it and had several concerns that were not resolved within that �hour. The proposal has not progressed further since then.
