encoding - How to convert from full-width to half-width Japanese characters in Java? -

i'm using class transliterator of icu project convert half-width full-width characters this:

transliterator transliterator = transliterator.getinstance("hiragana-katakana"); string converted = transliterator.transliterate("ｺﾝﾆﾁﾊ");  //half-width 

the result of converted is: コンニチハ (full-width)

but:

string converted = transliterator.transliterate("コンニチハ");  //full-width 

the result of converted still: コンニチハ (full-width)

my expectation ｺﾝﾆﾁﾊ. can me solve this?

thanks.

i found answer here. it's simple using different params below:

transliterator transliterator = transliterator.getinstance("halfwidth-fullwidth"); string converted = transliterator.transliterate("ｺﾝﾆﾁﾊ");  //half-width 

converted value: コンニチハ

transliterator transliterator = transliterator.getinstance("fullwidth-halfwidth"); string converted = transliterator.transliterate("コンニチハ");  //full-width 

converted value: ｺﾝﾆﾁﾊ
