名前	型	方向	説明
set	USet*	in	対象のUnicodeセット。
itemIndex	INT	in	取得する項目の0始まりインデックス。
start	INT*	inout	範囲項目の場合、先頭コードポイントを受け取る出力ポインタ。
end	INT*	inout	範囲項目の場合、末尾コードポイントを受け取る出力ポインタ。
str	WORD*	inout	文字列項目の場合、文字列を書き込む出力バッファへのポインタ。
strCapacity	INT	in	strバッファの容量(UChar単位)。
ec	UErrorCode*	inout	エラーコードを受け取るUErrorCodeポインタ。呼び出し前にゼロ初期化が必要。
