What is the default encoding for javac in Linux?

Question

javac says

If the -encoding option is not specified, then the platform default converter is used.

I guess the default encoding in Linux is UTF-8, how to get the default encoding in Linux?

Answer 1

javac will use the default encoding with which it has been configured. Often this corresponds to whatever your system's default locale "codeset" happens to be, but there actually is no guarantee that they are the same. The JVM does not pay attention to the locale environment variables.

The term "codeset" is (almost) synonymous with "charset set" or "encoding".

Answer 2

Not sure if that's what you're asking, but you can see your encodings by running locale. Example:

malice@Haskell ~ $ locale
LANG=en_US.utf8
LC_CTYPE="en_US.utf8"
LC_NUMERIC="en_US.utf8"
LC_TIME="en_US.utf8"
LC_COLLATE="en_US.utf8"
LC_MONETARY="en_US.utf8"
LC_MESSAGES="en_US.utf8"
LC_PAPER="en_US.utf8"
LC_NAME="en_US.utf8"
LC_ADDRESS="en_US.utf8"
LC_TELEPHONE="en_US.utf8"
LC_MEASUREMENT="en_US.utf8"
LC_IDENTIFICATION="en_US.utf8"
LC_ALL=

on ubuntu 14 , you can use this quick command:

    # env |grep LANG
