The mixed_script_confusables lint detects visually confusable characters in identifiers between different scripts.


// The Japanese katakana character エ can be confused with the Han character 工.
const エ: &'static str = "アイウ";



This lint warns when characters between different scripts may appear visually similar, which can cause confusion.

If the crate contains other identifiers in the same script that have non-confusable characters, then this lint will not be issued. For example, if the example given above has another identifier with katakana characters (such as let カタカナ = 123;), then this indicates that you are intentionally using katakana, and it will not warn about it.

Note that the set of confusable characters may change over time. Beware that if you “forbid” this lint that existing code may fail in the future.
