pub fn pgettext<T, U>(msgctxt: T, msgid: U) -> String where
T: Into<String>,
U: Into<String>,
Translate msgid to localized message from the default domain (with context support).
Panics if:
msgctxt or msgid contain an internal 0 byte, as such values can’t be passed to the
underlying C API;- the result is not in UTF-8 (see this note).
