在 FileZilla Server 的第一個支援 UTF-8 的版本上頭, 是變成一個只支援 UTF-8 的程式. 所以你必須使用支援 UTF-8 的 client 來連線. 這個在英文語系國家, 當然不會有什麼問題, 不過... 在我們這種非英文語系的國家, 就變成沒有支援 UTF-8 的 ftp client 完全不能用了.

所以, 作者後來又改了程式, 加上 OPTS UTF8 ON/OFF 的支援. 不過... 預設的情況, 仍是開啟 UTF-8 的支援. 所以... 對我們來說, 雖然進了一小步, 但仍然得到相同的結果, 因為... 不支援 UTF-8 的 ftp client, 根本不知道要送出 OPTS UTF8 OFF 來把 UTF-8 的支援關掉. 且... 真的知道要這樣做的 client, 想必也是已經支援 UTF-8 了吧, 既然支援 UTF-8, 那也不需要去關掉這個功能.

因為這個功能, 在 RFC 上頭, 並沒有詳細的規定,  所以作者似乎為了遵守 RFC 上頭的規定, 並不打算把程式改成與一般的 ftp server 一樣, 一開始不採用 UTF-8, 等到收到了 OPTS UTF8 ON 才去使用 UTF-8.

這個 patch 就是用來修改這個小問題:

http://www.teatime.com.tw/~tommy/FileZillaServer.zip  

另外, 在 FileZilla 上頭, 對於伺服器是 FileZilla Server 時, 並不會送出 OPTS UTF8 ON 指令. 所以,  我們也必須修改 FileZilla 才能支援上頭修改過的伺服器:
