How to find out what Unicode are available in your system?

[RC]

I tried

System.out.println(System.getProperty("file.encoding"));
System.out.println(System.getProperty("file.encoding.pkg"));
System.out.println(System.getProperty("sun.io.unicode.encoding"));
System.out.println(System.getProperty("sun.jnu.encoding"));

got output

Cp1252
sun.io
UnicodeLittle
Cp1252

I have no idea what they mean.

I would like to find out ALL available unicode names such Big5, GB2312,
ISO-8859-1, UTF-16, UTF-8, etc. in the system.
Anyone out there has any idea how to find these availabel unicode
names?

Thank Q in advance!

I tried

System.out.println(System.getProperty("file.encoding"));

The default character encoding of your operating system. Java uses it
when you convert between characters and bytes, but don't give an
explicit encoding.

System.out.println(System.getProperty("file.encoding.pkg"));
System.out.println(System.getProperty("sun.io.unicode.encoding"));
System.out.println(System.getProperty("sun.jnu.encoding"));

I think these are internal details of Sun's implementation of Unicode
character-sets. You should have no business here.

got output

Cp1252
sun.io
UnicodeLittle

Use Charset.availableCharSets() of package java.nio.charset

Use Charset.availableCharSets() of package java.nio.charset

Thank Q for your help!

Then you might want to read the Internet RFCs 2045, 2046, 2047, 2048.
These will give you a good understanding of character sets as they are
used on the Internet.

All available character set names are available at
<http://www.iana.org/assignments/character-sets>.

java.util.Locale has a method that will return an array of all available
locales and/or ISO language codes. You may then be able to transform
these into character set names, using the MimeUtility class of the
javamail add-on package available from Sun.
