$encoded_filename について、ファイル名に含まれる改行文字が除去されていません。header 関数に渡す文字列に改行文字を許容すると HTTP ヘッダインジェクションが可能になる場合があるため、$filename と $encoded_filename の両方とも改行文字が含まれないように修正して下さい。

IE8 での挙動について、filename に URL エンコードされた UTF-8 の文字列を渡すことでマルチバイト文字を含むファイル名でも文字化けせずに表示されることを確認したため、Content-Disposition ヘッダについてはリクエストの User-Agent に関わらず常に下記のようなヘッダを返すように修正して下さい。
Content-Disposition: attachment; filename="%E6%97%A5%E6%9C%AC%E8%AA%9E.txt"; filename*=utf-8''%E6%97%A5%E6%9C%AC%E8%AA%9E.txt
