如何在Java中将TIS-620字符串转换为UTF-8字符串？

如何在Java中将TIS-620（扩展ASCII泰国字符代码页）字符串转换为UTF-8字符串

import java.nio.ByteBuffer
import java.nio.CharBuffer

作为编码参数“UTF-8”传递

---

此外，您可能需要将charsets.jar放在类路径上以支持TIS620编码。

仍然不太正确！！！

public static ByteBuffer toByteBuffer(String content, String encode) {  
      Charset charset = Charset.forName(encode);  
      ByteBuffer bb = charset.encode(content);  
       return bb;  
   }  

private byte[] convertTis620ToUTF8(byte[] encoded)
{
    try
    {
        String theString = new String(encoded, "TIS620");
        return theString.getBytes("UTF-8");
    } 
    catch(UnsupportedEncodingException uee)
    {
        /* Didn't work out */
    }
}

...

byte[] utf8 = convertTis620ToUTF8(tis620);
