Maybe codec bug in MS1252, i.e., encoding Cp1252

[Eric Liang]

Hi all,
I've recently got an encoding error while using Cp1252 with UTF-8, the
string converted from UTF-8 to Cp1252 can not be converted back:

    String name1 = new String( new String("兆源").getBytes("UTF-8"),
    "Cp1252");
    String name2 = new String( name1.getBytes("Cp1252"), "UTF-8");

It looks like that there are some incorrect codes in jdk on encoding
Cp1252, and the related codes are:

    0x83    0x0192    ;Latin Small Letter F With Hook
    0x8d    0x008d
    0x8f    0x008f
    0x90    0x0090
    0x9d    0x009d

    ( from the Cp1252->UTF-8 map in
    http://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WindowsBestFit/bestfit1252.txt
    )

After I cloned the repository in http://hg.openjdk.java.net/jdk6/jdk6
and fix these codes in MS1252.java, the encoding error has gone.

I guess this is the right place to discuss this problem, and the patch
is in the attachment. Anyone with any comment is appreciated.

Regards,
Eric
