How to display chinese character

I am not sure about S60 emulators, but at least with the UIQ emulators you can just take a TrueType font with Chinese characters, copy it to the Z:\Resource\font directory of the emulator, and that's it.

I am using Simsun.ttf. Just hunt it down with Google if you want it.

Why do you make your life hard when you don't have to?

Nobody here told you to *convert* the TrueType font to anything. There is no need to convert it because S60 3rd edition phones can work directly with TrueType fonts, If you give them the same name as the built-in system font, you can even coax your phone into using any old TrueType font as your system font for all messages, menus and so on, as explained e.g. here:

So just copy a TrueType font to the Z:\Resource\Fonts directory of the emulator (plural, with "s", my first take with Z:\Resource\Font was wrong) , select that font in your program for whatever you want to display in Chinese, and that's it.

Of course if you don't correctly select the font in your program, all the presence of a Chinese font won't help a bit, so maybe there is the problem?
