Subject: 31.0.50; Gnus summary doesn't display unicode glyphs anymore
Date: Mon, 25 Aug 2025 23:01:59 +0200

I've rebuild Emacs (commit 21b072c6074466f3ec7d2489b82e21d8b0cae265) and
now Gnus doesn't display unicode glyphs anymore in the summary buffer. I
went back to commit bb0ede711eb630e3cc4b02316bf76079ce760de6 and the
glyphs work again. Eli, could this be related to the recent display
table changes? Thank you!

I don't use Gnus, so I will need a recipe starting from "emacs -Q" to
investigate this.

Thanks.

Okay, thanks. I will do when I find time to investigate further. For now
I had to roll back to the working commit
bb0ede711eb630e3cc4b02316bf76079ce760de6. The commits are only a few
days apart. The only commits which stood out are some changes to
redisplay and the string resizing change which has caused other minor
issues. Maybe this already helps. I only used
21b072c6074466f3ec7d2489b82e21d8b0cae265 briefly and I had noticed the
issue only in Gnus and not in other buffers.

Thanks.  Please see if the change I installed for bug#79317 also fixed
this problem.
