Typos in Sym Document: \u{d8__}

These codepoints are not valid in Unicode/ISO/IEC Standards.

And I try to find some info, but get none.

path/to/typst0140-main$ grep "ballot" . -r
./docs/changelog/0.12.0.md:  `ballot.check`, `ballot.check.heavy`, `emptyset.bar`, `emptyset.circle`,
./docs/changelog/0.12.0.md:- Renamed: `turtle` to `shell`, `notes` to `note`, `ballot.x` to `ballot.cross`,
path/to/typst0140-main$ grep "D83D" . -r
path/to/typst0140-main$ grep "d83d" . -r
path/to/typst0140-main$

It’s in codex. But the codepoint is correct there (U+1F5F9 for the heavy checkmark), and it works when you use the symbol to make a PDF, so it seems to be an issue with the documentation only. Maybe file an issue…
