native2ascii [ options ] [ inputfile [ outputfile ]]
native2ascii is a simple program that reads a text file (usually of Java source code) encoded using a local encoding and converts it to a Latin-1-plus-ASCII-encoded-Unicode form allowed by the Java Language Specification. This is helpful when you must edit a file of Java code but do not have an editor that can handle the encoding of the file.
The inputfile and outputfile are optional. If unspecified, standard input and standard output are used, making native2ascii suitable for use in pipes.
