示例1: currentCodePoint
import com.ibm.icu.text.UTF16; //导入方法依赖的package包/类
/**
* Returns the current codepoint
* @return current codepoint
*/
@Override
public int currentCodePoint(){
// cannot use charAt due to it different
// behaviour when index is pointing at a
// trail surrogate, check for surrogates
int ch = current();
if(UTF16.isLeadSurrogate((char)ch)){
// advance the index to get the next code point
next();
// due to post increment semantics current() after next()
// actually returns the next char which is what we want
int ch2 = current();
// current should never change the current index so back off
