Thanks for looking into it!
Out of curiosity, what fonts do you have installed? When I search for
fonts on my system that provide OCTAGONAL SIGN, I only get one match:
$ fc-list :charset=0x1F6D1
/usr/share/fonts/truetype/noto/NotoColorEmoji.ttf: Noto Color
Emoji:style=Regular
(from the fonts-noto-color-emoji package)
It looks like st does glyph-scavenging so it can display glyphs that
aren't in the selected font; perhaps it's not prepared to handle fonts
that provide colour bitmaps.
(I notice xterm added glyph-scavenging support in version 338 on 2018-
12-09, and subsequent versions have added various checks and safeguards
to avoid colour bitmap fonts rather than support them)
