Problem to enter Chinese to Outlook 2003 contact fields

[Calvin]

I can read/write Chinese everywhere in Office 2003 except the system does not
allow me to enter/display Chinese characters in Outlook 2003 contact record
fields.

When creating a new contact record, the lang. bar will not switch to
Chinese. If I force input method to Chinese by using the hot key sequence, I
was able to enter the Chinese characters temporary, but as soon as I save the
record, all the chinese characters are saved and display as ???.

Please help, thanks
