there are often subtle differences, but upper() and lower() are much
more likely to produce right results than collation order or date/money
formats.
in fact seem to be only 10 distinct LC_CTYPE files for ~110 locales with
most european-originated languages having the same and only
tr_TR, zh_??, fr_??,da_DK, de_??, ro_RO, sr_YU, ja_JP and ko_KR having
their own.

As I understand it, a locale should cover all locale-specific issues

Are these ASCII and European characters uppercased in some
Japanese-specific way ?
