java字符編碼探究相關(guān)小函數(shù)*

*

*UTF-16charset使用16位量，因此對(duì)字節(jié)挨次敏感。流的字節(jié)挨次可以由Unicode字符’\uFEFF’

*所表示的初始字節(jié)挨次標(biāo)記來(lái)指示。

*

*UTF-16BE16位UCS轉(zhuǎn)換格式，BigEndian（最低地址存放高位字節(jié)）字節(jié)挨次

*UTF-16LE16位UCS

*轉(zhuǎn)換格式，Little-endian（地址存放低位字節(jié)）字節(jié)挨次

*

*java中假如沒有feff的標(biāo)志，則默認(rèn)為feff
