下面是我 _vimrc 有關 encoding 的設定，
開啟大部份的檔案都沒問題，
不知大家有沒有更好的設定？
vim 的編碼偵測常常出錯，
一開始我是用 FencView 來補強。
但是我發現如果是 cp936 的文檔中含有日文字，
FencView 會用 cp932 的編號去開。
因為我找到的日文歌詞多是 cp936 的碼，
所以後來我把 FencView 的自動偵測關掉，
直接由 fileencodings 的順序來決定。
如果還有錯，就用 FencView 增加的選單來改編碼。
FencView 的 bug 我已經於去年十月就通報給作者，
不過目前還沒更新。
我試過一些不同的設定，大家可以參考下面的網址，
紅色代表編碼偵測錯誤。

P.S. 這樣會強制使用英文選單。
P.S.2 記得加在 _vimrc 最前面才有效。
P.S.3 status line 的設定我再另外開一篇文章。
BOM 是標準 unicode 檔加在檔頭的辨識符號。
不過一些 HTML, XML, and Tex's 的 compilers
無法處理含有 BOM 的檔，因此下面的設定是預設為
開新檔時內定格式為 utf-8, 但不儲存 BOM。
開啟舊檔時則依原來的設定儲存。
如果新檔要用 BOM，可以在存檔前下 :set bomb 指令。
我是建立一個 "SaveAs" hotkey 每次另存新檔時提供選項。
