Fix ICE in suggestion caused by `⩵` being recovered as `==` The second suggestion shown here would previously incorrectly assume that the span corresponding to `⩵` was 2 bytes wide composed by 2 1 byte wide chars, so a span pointing at `==` could point only at one of the `=` to remove it. Instead, we now replace the whole thing (as we should have the whole time): ``` error: unknown start of token: \u{2a75} --> $DIR/unicode-double-equals-recovery.rs:1:16 \| LL \| const A: usize ⩵ 2; \| ^ \| help: Unicode character '⩵' (Two Consecutive Equals Signs) looks like '==' (Double Equals Sign), but it is not \| LL \| const A: usize == 2; \| ~~ error: unexpected `==` --> $DIR/unicode-double-equals-recovery.rs:1:16 \| LL \| const A: usize ⩵ 2; \| ^ \| help: try using `=` instead \| LL \| const A: usize = 2; \| ~ ``` 2024-07-16 22:43:30 +00:00			`const A: usize ⩵ 2;`
