// ISO C++ 14882: 22.1 Locales

// because those masks do not conform to the requirements of 22.2.1.
// In particular, a separate 'print' bitmask does not exist (isprint(c)
// relies on a combination of flags) and the '_ALPHA' mask is also a

// masks here, based on the generic masks, and the corresponding
// classic_table in ctype_noninline.h.
