Perhaps you could give an example of what "international characters" are, and tell us what is a non-international character.

    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".

      Usually? No they don't. They usually call them "non-ASCII characters" or "Unicode characters" - the latter being inaccurate because the ASCII characters are also in Unicode.

      And even if people did usually call non-ASCII characters "international characters" it's still inaccurate and therefore not helpful, because "d" is both an ASCII and an international character. You can see how international it is by referring to a French, German, English, Spanish, Vietnamese, Polish etc dictionary.
