パラメーター

名前	型	方向	説明
id	WORD*	in	正規化する元のタイムゾーンID(UTF-16)を指す。
len	INT	in	idの長さをUChar単位で指定する。-1でNUL終端。
result	WORD*	inout	正規タイムゾーンIDを格納するUTF-16出力バッファを指す。
resultCapacity	INT	in	resultの容量をUChar単位で指定する。0で必要量取得。
isSystemID	CHAR*	inout	システム定義IDか否かを受け取る真偽値ポインタ。NULL可。
status	UErrorCode*	inout	ICUエラーコードを入出力するポインタ。呼出前に成功値で初期化する。
