Really weird. As a native Chinese, I never see those digits used as part of the Chinese language. And those digits all are only present in the Chinese official encoding GB18030, but not in previous ones (GB2312 and GBK). I have no idea about why subscripts 1-4 is special. -- Best regards, lilydjwg Linux Vim Python 我的博客 http://lilydjwg.is-programmer.com/ -- You received this message from the "vim_dev" maillist.
