      com.vgrs.xcode.cmdline.idna.PunycodeCmdLine

public class PunycodeCmdLine
extends CmdLine

This tool compresses and converts Unicode data into an ASCII compatible sequence. This algorithm was designed for use with IDNA. No other ACE encoding is supported by the IETF. The IDNA RFC gives applications permission to choose whether or not to exclude ASCII characters which are not a letter, digit, or hyphen. If the –3 switch is given, these codepoints are allowed to be encoded by Punycode.

Usage: com.vgrs.xcode.cmdline.idna.PunycodeCmdLine [-3] (--encode | --decode) file=[file name]

• -3 => do NOT enforce Std 3 Ascii Rules
