Greek and other sybols in msgbox excel

Question

when i'm trying to put in msgbox smth like 0,1 ≤ β ≤ 0,56. Instead of this it shows me 0.1???0.56. How to force it to show normaly?

Sub test()

    Range("A16") = 0.1 & ChrW(8804) & ChrW(946) & ChrW(8804) & 0.56 'Works correct
    MsgBox 0.1 & ChrW(8804) & ChrW(946) & ChrW(8804) & 0.56 'Shows 0.1????0.56

End Sub
