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
