==================== Native2ASCII.exe
Native2ASCII - Native-to-Ascii Converter
Converts a file with native-encoded Characters (Characters Which Are Non-Latin 1 and Non-Unicode) To one with uncode-encoded characters.
Synopsis
Native2ASCII [Options] [InputFile "] Description
The Java compiler and other Java tools can only process files which contain Latin-1 and / or Unicode-encoded (/ udddd notation) characters. Native2ascii converts files which contain other character encodings into files containing Latin-1 and / or Unicode-encoded charaters .
If OUTPUTFILE IS OMITTED, Standard Output IS Used for Output. IF, IN Addition, InputFile IS omitted, Standard INPUT INPUT INPUT INPUT.
Options
-reverse Perform The Reverse Operation: Convert a file with latin-1 and / or uncode encoded characters to one with native-encoded characters.
-encoding encoding_name Specify the encoding name which is used by the conversion procedure. The default encoding is taken from System property file.encoding. The encoding_name string must be taken from the first column of the table of supported encodings in the Supported Encodings document.
-Joption Pass option to the Java virtual machine, where option is one of the options described on the reference page for the java application launcher. For example, -J-Xms48m sets the startup memory to 48 megabytes.
