Oops! Looks like there is problem with attachment (might be because I
attached .class file as well). I'm pasting the fix and test program
here in mail.
Test Program:
import java.nio.charset.*;
class PrintDefaultCharset {
public static void main(String[] args) {
System.out.println("LANG = "+System.getenv("LANG"));
System.out.println("Default charset =
"+Charset.defaultCharset().name());
System.out.println("file.encoding =
"+System.getProperty("file.encoding"));
System.out.println("sun.jnu.encoding =
"+System.getProperty("sun.jnu.encoding"));
}
}
Fix:

Subject: [AIX] Fix codepage mappings in Java for IBM-943 and Big5
Hi All,
This issue is continuation to bug 8201540 (Extend the set of
supported charsets in java.base on AIX) in which we have moved
default charsets of most of the locales supported by Operating System
to java.base module thus enabling OpenJDK on those locales for AIX
platform.
As part of that, charsets for locales Ja_JP (IBM-943) and Zh_TW
(big5) also have been moved. However, corresponding charsets mapped
in Java is not correct for them on AIX. Following are the details:
1. IBM-943 [1] for locale Ja_JP should be mapped to IBM-943C [2]
Fundamental difference between IBM-943 and IBM-943C is that IBM-943C
is ASCII compatible which means code points 'yen' and 'overline' of
IBM-943 is replaced with 'backslash' and 'tilde' from ASCII character
set.
2. Big5 for locale Zh_TW should be mapped to IBM-950 [3]
I've attached simple test program to print the default charset along
with fix for this issue. When run test program (PrintDefaultCharset)
with IBM JDK 8 (on AIX) for locales Ja_JP & Zh_TW, following is
output.
-bash-4.4$ LANG=Ja_JP ~/JDKs/IBM/80/ON/sdk/jre/bin/java
PrintDefaultCharset
LANG = Ja_JP
Default charset = x-IBM943C
file.encoding = IBM-943C
sun.jnu.encoding = IBM-943C
-bash-4.4$ LANG=Zh_TW ~/JDKs/IBM/80/ON/sdk/jre/bin/java
PrintDefaultCharset
LANG = Zh_TW
Default charset = x-IBM950
file.encoding = IBM-950
sun.jnu.encoding = IBM-950
Same test run with openJDK 11 gives following output
-bash-4.4$ LANG=Ja_JP ~/jdk/bin/java PrintDefaultCharset
LANG = Ja_JP
Default charset = x-IBM943
file.encoding = IBM-943
sun.jnu.encoding = IBM-943
-bash-4.4$ LANG=Zh_TW ~/jdk/bin/java PrintDefaultCharset
LANG = Zh_TW
Default charset = Big5
file.encoding = big5
sun.jnu.encoding = big5
