native2ascii - Encoding Converter Command and Options
This section describes the native-to-ASCII encoding converter 'native2ascii' and its options. Non-ASCII characters in a Java source file must be converted into \udddd Unicode sequences before giving it to the Java compiler.
Warning: "native2ascii" has been discontinued since JDK 9. But if you still have JDK 1.8 installed, you can continue to use it to convert Java source from one encoding to another.
What Is "native2ascii"? "native2ascii" is a command line tool that reads a text file stored in a non-ASCII encoding and converts it to an ASCII text file. All non-ASCII characters will be converted into \udddd sequences, where dddd is the Unicode code value of the non-ASCII character.
"native2ascii" has been included in JDK installation since JDK 1.2. And it is represented by the %java_home%\bin\native2ascii.exe program file.
"native2ascii" is an important Java tool, because Java compiler and other Java tools can only process files which contain ASCII characters and \udddd Unicode code sequences.

"native2ascii" has the following command syntax:
