I often mix English words in my Chinese texts. When doing that, I want to add a space before the English words. For example:
XXXX wwwww wwwww wwwww XXXX *
where X's are Chinese characters and w's are English letters.
The only problem is the space marked *, where the Chinese characters end and the English words start. Latex seems to swallow up that space, but I want it to be there.
Is there an automatic command that can handle this?
PS: right now my solution is to manually add a space by '\ ' whenever I insert English.
