Question

Is there any mapping table between windows code and java charset?

Java Charset list

Windows Code page list

Why I want that: I have to read and analyse a binary file which contains part:

0x00 word codepage like 1252, 936, 65001 I knew, and also 50222 I did not know.
0x02 word string length
0x04 bytes null-terminated string 
...more strings...

I wrote the code:

int codepage = read16(inputStream);
int length = read16(inputStream);
byte[] bytes = new byte[length];
inputStream.read(bytes, 0, length);
String str = new String(bytes, getCharsetFromCodepage(codepage));

and getCharsetFromCodepage is what I want.
