此功能内置在Character.UnipreBlock类中。与日语相关的Unipre块的一些示例：
Character.UnipreBlock.of('誰') == CJK_UNIFIED_IDEOGRAPHSCharacter.UnipreBlock.of('か') == HIRAGANACharacter.UnipreBlock.of('フ') == KATAKANACharacter.UnipreBlock.of('ﾌ') == HALFWIDTH_AND_FULLWIDTH_FORMSCharacter.UnipreBlock.of('！') == HALFWIDTH_AND_FULLWIDTH_FORMSCharacter.UnipreBlock.of('。') == CJK_SYMBOLS_AND_PUNCTUATION但是，一如既往，魔鬼在细节中：
Character.UnipreBlock.of('Ａ') == HALFWIDTH_AND_FULLWIDTH_FORMS哪里
Ａ是全角字符。因此，这与
ﾌ上面的半角片假名属于同一类别。请注意，全角
Ａ与常规（半角）不同
A：
Character.UnipreBlock.of('A') == BASIC_LATIN
