What is the technically correct way of referring to "high ascii" or "extended ascii" characters? I don't just mean the range of 128-255, but any character beyond the 0-127 scope.

Often they're called diacritics, accented letters, sometimes casually referred to as "national" or non-English characters, but these names are either imprecise or they cover only a subset of the possible characters.

What correct, precise term that will programmers immediately recognize? And what would be the best English term to use when speaking to a non-technical audience?
