标题[vim ] 编码问题及 Unicode BOM 设定
时间Fri Jan 29 23:03:36 2010
下面是我 _vimrc 有关 encoding 的设定，
开启大部份的档案都没问题，
不知大家有没有更好的设定？
vim 的编码侦测常常出错，
一开始我是用 FencView 来补强。
但是我发现如果是 cp936 的文档中含有日文字，
FencView 会用 cp932 的编号去开。
因为我找到的日文歌词多是 cp936 的码，
所以後来我把 FencView 的自动侦测关掉，
直接由 fileencodings 的顺序来决定。
如果还有错，就用 FencView 增加的选单来改编码。
FencView 的 bug 我已经於去年十月就通报给作者，
不过目前还没更新。
我试过一些不同的设定，大家可以参考下面的网址，
红色代表编码侦测错误。

P.S. 这样会强制使用英文选单。
P.S.2 记得加在 _vimrc 最前面才有效。
P.S.3 status line 的设定我再另外开一篇文章。
BOM 是标准 unicode 档加在档头的辨识符号。
不过一些 HTML, XML, and Tex's 的 compilers
无法处理含有 BOM 的档，因此下面的设定是预设为
开新档时内定格式为 utf-8, 但不储存 BOM。
开启旧档时则依原来的设定储存。
如果新档要用 BOM，可以在存档前下 :set bomb 指令。
我是建立一个 "SaveAs" hotkey 每次另存新档时提供选项。
