Function ncursesw::use_legacy_coding

pub fn use_legacy_coding(level: Legacy) -> Result<Legacy, NCurseswError>

Override locale-encoding checks.

The use_legacy_coding() function is an extension to the NCurses library. It allows the caller to change the result of unctrl(), and suppress related checks within the library that would normally cause nonprinting characters to be rendered in visible form. This affects only 8-bit characters.
