Getting the default charset.

Hi,

I need to get the default charset of the platform that I am using. I found a workaround by using an InputStreamReader with the required parameters and calling getEncoding() method. After this, I can user Charset.forName(...). On Windows platform, I get "Windows-1252". That's ok.

This solution works but, maybe someone knows a simpler way to get the same information. This is what I would like to know.

Thanks !

I can't say how reliable, universal, or accurate this is, but System.getProperty("sun.jnu.encoding") gives me the value of Cp1252 in my machine, as expected.

what is the meaning of a character set anyway?

It is the set of character that is used for displaying or document encoding like an XML document (inside the header tag ?xml). Charset class Javadoc shows the character sets supported by Java. see: http://java.sun.com/j2se/1.4.2/docs/api/index.html

Thank you for your help ChuckBing.As you say, went I see a property beginning with "sun.xxxxx" I am expecting that it could be Sun specific.Bye

Is there a way to find the character set of a specific file? The program im writing may get input as files that may be either in ASCII or UNICODE format? how can i determine either of the formats?

As a start, check this page that discusses Unicode and byte order marks (BOM) http://mindprod.com/jgloss/unicode.html

Just been looking for exactly the same thing, so Google led me here. It also lead me to this:

http://java.sun.com/j2se/1.5.0/docs/api/java/nio/charset/Charset.html

In Java 1.5 ( but not in earlier versions), the Charset class contains a defaultCharset() static method, defined when the JVM starts up.

Hope this helps.
