Not a defect when
The zero-width or soft-hyphen character is the intended payload, such as test data exercising Unicode handling, and the code around it says so.
What it reads
Clippy, with the compiler behind it. The only pass that compiles.
Tier
Serious: worth interrupting other work for.
The tier bounds how severe a rule may be; its category bounds the tier.Diff scope
The changed line itself.
What--scope contextual looks at to decide whether a change caused the finding.Change it
Turn it off, or make it blocking, without touching the code it flags:
rust-doctor --rule clippy::invisible_characters=off .
rust-doctor --rule clippy::invisible_characters=error .
