最近,做一个关于SMS的程序,需要对中文部分进行UCS编码,这里用了两个函数,可以将短信中的UCS2字符串在UCS2和GBK之间装换。记录以下代码:
/**
* UCS2解码
*
* @param src
* UCS2 源串
* @return 解码后的UTF-16BE字符串
*/
public static String DecodeUCS2(String src) {
byte[] bytes = new byte[src.length() / 2];
for (int i = 0; i < src.length(); i += 2) {
bytes[i / 2] = (byte) (Integer
.parseInt(src.substring(i, i + 2), 16));
}
String reValue;
try {
reValue = new String(bytes, "UTF-16BE");
} catch (UnsupportedEncodingException e) {
throw new PduDecodeException(e);
}
return reValue;
}
/**
* UCS2编码
*
* @param src
* UTF-16BE编码的源串
* @return 编码后的UCS2串
*/
public static String EncodeUCS2(String src) {
byte[] bytes;
try {
bytes = src.getBytes("UTF-16BE");
} catch (UnsupportedEncodingException e) {
throw new PduEncodeException(e);
}
StringBuffer reValue = new StringBuffer();
StringBuffer tem = new StringBuffer();
for (int i = 0; i < bytes.length; i++) {
tem.delete(0, tem.length());
tem.append(Integer.toHexString(bytes[i] & 0xFF));
if(tem.length()==1){
tem.insert(0, '0');
}
reValue.append(tem);
}
return reValue.toString().toUpperCase();
}
