Encoding from UTF-8 encoded String to Microsoft Project default encode

Question

Hi Expert ...
I have a problem with encoding a String from UTF-8 String in order to write a MPX (Microsoft Project) file. I used UTF-8 on my Database encoding, and I want to write a MPX file using MPXJ library, but the result is (?) character. I think it's because I didn't encode yet to Shift JIS (a Microsoft Product default encoding). And after that I try to encode the String with Shift_JIS encoding, but the same result is appeared. I try to looking another way, but there is no result.
I hope some expert would help me to solve this problem.
Thank you,
Alfian B.

Totally wrong. A String doesn't have an encoding.
Now if you had an array of bytes, which were encoded using one charset, and you wanted to convert that to an array of bytes encoded using a second charset, you would use code like this:byte[] bytes = // the bytes encoded in UTF-8, let's say
String s = new String(bytes, "UTF-8"); // make that into a String
byte[] newbytes = s.getBytes("windows-31j"); // encode the String into windows-31j
