## Summary
Currently, [this
line](716688d44e/crates/ruff_linter/src/fix/edits.rs (L101))
assumes that the `noqa` comment begins with an octothorpe followed by a
space. (`# `) With anyone's random code, this of course is not always
true.
When there's a multi-byte character after the leading octothorpe, such
as
[`\u0085`](https://www.fileformat.info/info/unicode/char/85/index.htm),
we try slicing from within the character, causing a panic.
To fix this, the logic has been changed to remove unused `noqa`
directives and keep any trailing comments, or removing the whole comment
if the comment is just the unused `noqa`
Fixes #10097.
## Test Plan
`cargo test`
