看注释
大陆用GB,台湾用BIG5,记得很多台湾游戏都是BIG5码,看不懂吗
function GBtoBIG5(value: string): string; //从国标转化为BIG5编码
function BIG5toGB(value: string): string; //从BIG5转化为国标
function isGB(value: string): Boolean; //判断是否是国标编码格式
function isBIG5(value: string): Boolean; //判断是否是BIG5编码格式用途感觉应该是为了使字符串能正常显示出来进行必要的转化,具体不是很清楚,知道的请多说点呀
你用不到,不等于这个功能就没用,你就把它当成翻译把,说一句BIG5的话,通过他翻译成普通话给你听
这样就能明白了 Thank you bdmh
