+ # flag is on. On ASCII platforms, the high ordinals are all the
+ # non-ASCII's. On EBCDIC platforms, we don't include in these the non-ASCII
+ # controls whose ordinals are less than SPACE, excluded below by the range
+ # \0-\x3f. On ASCII platforms this range just compiles as part of :ascii:.
+ # On EBCDIC platforms, there is just one outlier high ordinal control, and
