パラメーター

名前	型	方向	説明
algorithmicType	UConverterType	in	変換先のアルゴリズム型コンバーター種別(UTF-8等)を示す列挙値。
cnv	UConverter*	inout	変換元(外部符号化→Unicode)のコンバーターへのポインタ。
target	LPSTR	in	変換結果を受け取る出力バッファ。
targetCapacity	INT	in	targetバッファのバイト容量。
source	LPCSTR	in	変換元のバイト列へのポインタ。
sourceLength	INT	in	sourceのバイト数。-1でNUL終端を意味する。
pErrorCode	UErrorCode*	inout	エラーコードを入出力するポインタ。事前にU_ZERO_ERRORで初期化する。
