How do I display Unicode Text on UserForm.Caption

Hi ,all.
I can display Uniocode Text on UserForm1.Label1.Caption ,
but cannot UserForm1.Caption ?

e.g.
s = ChrW(&H7535) & ChrW(&H8BDD) & ChrW(0)
Me.Controls("Label1").Caption = s '<- This works correctly.
Me.Caption = s '<= This doesn't work. Caption becomes
two question marks.

Does anybody know how to work around this?
I tried to work around this with the followings by myself, but failed.
