パラメーター

名前	型	方向	説明
idna	UIDNA*	in	変換に用いる開いたUIDNAインスタンスを指す。
name	WORD*	in	ASCII形式へ変換するドメイン名全体を指す。
length	INT	in	nameの長さをUChar単位で指定する。-1でNUL終端。
dest	WORD*	inout	変換結果のASCIIドメイン名を格納する出力バッファ。NULL可。
capacity	INT	in	destの容量をUChar単位で指定する。0で事前長取得。
pInfo	UIDNAInfo*	inout	処理結果やエラーフラグを受け取るUIDNAInfo構造体を指す。
pErrorCode	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。
