Usually, people call symbols outside the set of the ASCII characters 32 to 126 "international characters". In the pre-Unicode times, the narrow definition was all characters with a code between 128 and 255, in one or more of the several ASCII extensions (ISO Latin-XXX, machine-specific character sets). Now, the narrow definition is all Unicode characters except those also defined as ASCII 32 to 126. The wider definition is and was always "every character used somewhere at some point in time".
