If a GUI honors it but the compiler does not
then the human sees one thing, the compiler another. If the compiler drops the control characters without warning, that can become a problem. e.g. it could be used to make you see 0x0F where the compiler sees 0xF0.
How feasibly any of this is is another matter. The example above is not very practical unless it hits a project that still uses literals for critical fields.
