Unicode转成中文

public String convert(String utfString){

StringBuilder sb = new StringBuilder();

int i = -1;

int pos = 0;

while((i=utfString.indexOf("\\u", pos)) !=-1){

sb.append(utfString.substring(pos,i));

if(i+5 < utfString.length()){

pos = i+6;

sb.append((char)Integer.parseInt(utfString.substring(i+2,i+6), 16));

}

return sb.toString();

}
