I think I should not mix different languages in a Chinese site. This is for the convenience of English readers.
To the best of my knowledge it is not advisible to mix different languages on the same websites. Most of the times, the pages on my Chinese blog will automatically set your browser to the correct coding scheme and type font though a charset command written into header of the page.
However, many readers especially from the western countries didn’t install appropriate Chinese type font in their PC. Therefore, what they see in the brower is dummy characters, usually little boxes or question marks.
