How to set Chinese font style in Tabularnote through journal

Hello,

I am trying to insert Chinese font in tabular note and for that i am using "Arial Unicode MS" font style.
Manually i am able to add Chinese font but when i use it through journal i am not able insert it.

I have used below code to set font style for Tabular note.

Dim fntMonoBT As Integer = workPart.Fonts.AddFont("Arial Unicode MS", FontCollection.Type.Standard)

After using this I am getting below result:
"Approved By / ??"

Where "??" represent Chinese word.

Offhand, here is my best guess:
Check your preferences: menu -> preferences -> user interface... -> journal -> journal file format; the option should be set to something other than ASCII. If the preference is set to ASCII, there may be information lost when reading the character.

I have checked in settings and Journal file format is set to Unicode.
