Expand description

Converts the argument to a LU string.

This forwards to the TryInto implementation on the argument, which means the macro is flexible and works with both string and wstring types, and both fixed and variable types, depending on context. Generally, to convert to a string type, pass a byte slice, and for a wstring type, pass a &str or String.
