49ef7e0638c8b771d8a136eae78b1c0f99acc8e0Garrett D'Amore * Please take careful note. It turns out that the _ISxxx macros
49ef7e0638c8b771d8a136eae78b1c0f99acc8e0Garrett D'Amore * occupy the lower order byte, except for _ISGRAPH, _ISALPHA, and _ISPRINT.
49ef7e0638c8b771d8a136eae78b1c0f99acc8e0Garrett D'Amore * Those occupt 0x2000, 0x4000, and 0x8000. Now, noting *very* carefully,
49ef7e0638c8b771d8a136eae78b1c0f99acc8e0Garrett D'Amore * it turns out that this leaves some gaps in the extended bits, which
49ef7e0638c8b771d8a136eae78b1c0f99acc8e0Garrett D'Amore * are occupied by _E1 = phonogram, _E2 = ideogram, and _E3 = English.
49ef7e0638c8b771d8a136eae78b1c0f99acc8e0Garrett D'Amore * The *other* _Ex bits are reserved. We don't think these higher order
49ef7e0638c8b771d8a136eae78b1c0f99acc8e0Garrett D'Amore * bits are baked into applications (because they haven't been used before),
49ef7e0638c8b771d8a136eae78b1c0f99acc8e0Garrett D'Amore * so we believe it is safe to reuse them how we see fit.
49ef7e0638c8b771d8a136eae78b1c0f99acc8e0Garrett D'Amore * This makes it possible to define a single space which overlaps both the
49ef7e0638c8b771d8a136eae78b1c0f99acc8e0Garrett D'Amore * wctype types, and the ctype types.
