native2ascii

文件轉碼工具，是將特殊各異的內容 轉為 用指定的編碼標準文體形式統一的表現出來

SYNOPSIS
?????? native2ascii [options] [inputfile [outputfile]]

DESCRIPTION
?????? native2ascii converts files that are encoded to any character encoding that is supported by the Java runtime environment? to
?????? files? encoded in ASCII, using Unicode escapes ("\uxxxx" notation) for all characters that are not part of the ASCII charac-
?????? ter set. This process is required for properties files containing characters not in ISO-8859-1 character sets. The tool? can
?????? also perform the reverse conversion.

?????? If? outputfile is omitted, standard output is used for output. If, in addition, inputfile is omitted, standard input is used
?????? for input.

OPTIONS
????????? -reverse
???????????? Perform the reverse operation: Convert a file encoded in ISO-8859-1 with Unicode escapes to a file? in? any? character
???????????? encoding supported by the Java runtime environment.

????????? -encoding encoding_name
???????????? Specifies? the? name? of the character encoding to be used by the conversion procedure. If this option is not present,
???????????? the default character encoding (as determined by the? java.nio.charset.Charset.defaultCharset? method)? is? used.? The
???????????? encoding_name? string must be the name of a character encoding that is supported by the Java runtime environment - see
???????????? the Supported Encodings @
???????????? http://docs.oracle.com/javase/7/docs/technotes/guides/intl/encoding.doc.html document.

????????? -Joption
???????????? Pass option to the Java virtual machine, where option is one of the options described on the reference page for the
???????????? java(1). For example, -J-Xms48m sets the startup memory to 48 megabytes.
