How to show pinyin characters(accented characters) in English Forum

[stageducky]

I have successfully enable the showing of Chinese characters in my English Forum. Now I wish to find a way to input "pinyin" characters such as (宜興荊溪新志, Yíxīng Jīngxī Xīnzhì) in my forum. I think its unicode but my forum is showing a "?" in place of the "special characters with the intonation marking above them".

Sarge, I'm sure you have the solution.

I have checked my collation, they are all latin1_swedish_ci.
