"Dictionary" + sorting (de-DE) is the default for German, but developers can specify the alternate "Phone + Book" sort (de-DE_phoneb) explicitly. + + Chinese BIG5 order: Ideographs are ordered according to the code point values of the Taiwanese + BIG5 industrial standard. + + Chinese radical/stroke order: Ideographs are ordered according to radical stroke count. + + Chinese Unicode order: Deprecated.

Identical to the default sort information used for English, + except that the backslash (\) is equal to the currency symbol, 0x00A5, the yen sign. + + Japanese XJIS order: Ideographs are ordered according to the code point values of the [JIS X + 208] and [JIS X 212] government standards. + + Korean KSC order: Ideographs are ordered according to the Korean Hangul pronunciation, as + specified in the Korean [KSC5601] government standard. + + Korean Unicode order: Deprecated.
