# Error code E0754

A non-ASCII identifier was used in an invalid context.

Erroneous code examples:

    mod řųśť; // error!

    #[no_mangle]
    fn řųśť() {} // error!

    fn main() {}

Non-ASCII can be used as module names if it is inlined or if a `#[path]` attribute is specified. For example:

    mod řųśť { // ok!
        const IS_GREAT: bool = true;
    }

    fn main() {}
