as3.0 character conversions (for Unicode character processing)

Flash game for the network communication, so that flash characters are used in the way of Unicode processing, in the absence of As3.0 itself to the Unicode character processing, I adopted the following processing methods

The Unicode string is converted to ByteArray:

Unicode string to ByteArray public static function Strtobytearray (strvalue:string, ulen:uint = 0): ByteArray {var byaa Ryr:bytearray = new ByteArray (); Byaaryr.endian = Endian.little_endian; for (var i:int = 0; i < strvalue.length; ++i) {Byaaryr.writeshort (Strvalue.charcodeat (i)), for (i = 0; i < (UL En-strvalue.length); ++i) {byaaryr.writeshort (0);} return byaaryr; }

ByteArray to Unicode string:

ByteArray to Unicode string public static function Byarraytostring (Byarray:bytearray): string {byarray.position = 0; v Ar strreturn:string = new String (); for (var i:int = 0; i < BYARRAY.LENGTH/2; ++i) {var strrep:string = Byarray.readmultibyte (2, "Unicode"); Strreturn = Replaceat (Strreturn, Strrep, I, I); return strreturn; }

as3.0 String Replacement:

public static function Replaceat (char:string, value:string, Beginindex:int, endindex:int): String {beginindex = Math.max (beginindex, 0); Endindex = Math.min (Endindex, char.length); var firstpart:string = char.substr (0, Beginindex); var secondpart:string = Char.substr (Endindex, char.length); Return (Firstpart + value + secondpart); }
