+Whether to respect the case of the file path when generating the route. Defaults to `false`, which means the route will be generated in lowercase. For example, `content/en-US/foo.md` will resolve to the `en-us/foo` path. This may not be what you expect.If set to `true`, the route will be generated with the same case as the file path. `content/en-US/foo.md` will resolve to the `en-US/foo` path.
