A character literal `?"` should be formatted to `'"'` but is actually converted to `'\"'`. This breaks the behavior of the code. The string literal `"\""` converted in the absence of `--plugins=plugin/single_quotes` is correct, so this case may not be taken into account. Environment: - Ruby: 3.1.4 - SyntaxTree: 6.1.1 - `--plugins=plugin/single_quotes`
