パラメーター

名前	型	方向	説明
context	void*	in	コールバックに渡される任意のユーザーデータ。NULL可。
fromUArgs	UConverterFromUnicodeArgs*	inout	Unicode→外部符号化変換の状態を保持する引数構造体へのポインタ。
codeUnits	WORD*	in	問題が生じたUnicodeコードユニット列(UTF-16)へのポインタ。
length	INT	in	codeUnitsの要素数。
codePoint	INT	in	対象のコードポイント。
reason	UConverterCallbackReason	in	コールバックが呼ばれた理由を示す列挙値。
err	UErrorCode*	inout	エラーコードを入出力するポインタ。SKIPでは該当文字を読み飛ばす。
