No, sometimes Japanese needs char ordering too and I think this is not
a Windows only problem. The real problem is Unicode defines char
orderes in totally random manner because Chinese/Japanese/Korean Kanji
characters are "Unified" in Unicode. To solve the problem, we can use
convert UTF8 to EUC_JP using CONVERT. See archives for more details.

Or you can use Unicode locale only if your platform's locale database
is not broken and you only use single locale.
