Spell Numbers to arabic Words

I am using the following VBA to spell numbers in arabic words !
however , the solution resulted to having the numbers spelled to ASCII codes .. Can anyone help?
Public Function SFormatNumber(ByVal x As Double) As String
Dim Letter1, Letter2, Letter3, Letter4, Letter5, Letter6 As String
Dim C As String
C = Format(Int(x), "000000000000")
Dim C1 As Double
C1 = Val(Mid(C, 12, 1))
Select Case C1
Case Is = 1: Letter1 = "واحد"
Case Is = 2: Letter1 = "اثنان"
Case Is = 3: Letter1 = "ثلاثة"
Case Is = 4: Letter1 = "اربعة"
Case Is = 5: Letter1 = "خمسة"
Case Is = 6: Letter1 = "ستة"
Case Is = 7: Letter1 = "سبعة"
Case Is = 8: Letter1 = "ثمانية"
Case Is = 9: Letter1 = "تسعة"
End Select


Dim C2 As Double
C2 = Val(Mid(C, 11, 1))
Select Case C2
Case Is = 1: Letter2 = "عشر"
Case Is = 2: Letter2 = "عشرون"
Case Is = 3: Letter2 = "ثلاثون"
Case Is = 4: Letter2 = "اربعون"
Case Is = 5: Letter2 = "خمسون"
Case Is = 6: Letter2 = "ستون"
Case Is = 7: Letter2 = "سبعون"
Case Is = 8: Letter2 = "ثمانون"
Case Is = 9: Letter2 = "تسعون"
End Select


If Letter1 <> "" And C2 > 1 Then Letter2 = Letter1 + " و" + Letter2
If Letter2 = "" Then
Letter2 = Letter1
End If
If C1 = 0 And C2 = 1 Then Letter2 = Letter2 + "ة"
If C1 = 1 And C2 = 1 Then Letter2 = "احدى عشر"
If C1 = 2 And C2 = 1 Then Letter2 = "اثنى عشر"
If C1 > 2 And C2 = 1 Then Letter2 = Letter1 + " " + Letter2
Dim C3 As Double
C3 = Val(Mid(C, 10, 1))
Select Case C3
Case Is = 1: Letter3 = "مائة"
Case Is = 2: Letter3 = "مئتان"
Case Is > 2: Letter3 = Left(SFormatNumber(C3), Len(SFormatNumber(C3)) - 1) + "مائة"
End Select
If Letter3 <> "" And Letter2 <> "" Then Letter3 = Letter3 + " و" + Letter2
If Letter3 = "" Then Letter3 = Letter2


Dim C4 As Double
C4 = Val(Mid(C, 7, 3))
Select Case C4
Case Is = 1: Letter4 = "الف"

Case 3 To 10: Letter4 = SFormatNumber(C4) + " الاف"
Case Is > 10: Letter4 = SFormatNumber(C4) + " الف"
End Select
If Letter4 <> "" And Letter3 <> "" Then Letter4 = Letter4 + " و" + Letter3
If Letter4 = "" Then Letter4 = Letter3
Dim C5 As Double
C5 = Val(Mid(C, 4, 3))
Select Case C5
Case Is = 1: Letter5 = "مليون"
Case Is = 2: Letter5 = "مليونان"
Case 3 To 10: Letter5 = SFormatNumber(C5) + " ملايين"
Case Is > 10: Letter5 = SFormatNumber(C5) + " مليون"
End Select
If Letter5 <> "" And Letter4 <> "" Then Letter5 = Letter5 + " و" + Letter4
If Letter5 = "" Then Letter5 = Letter4


Dim C6 As Double
C6 = Val(Mid(C, 1, 3))
Select Case C6
Case Is = 1: Letter6 = "مليار"
Case Is = 2: Letter6 = "ملياران"
Case Is > 2: Letter6 = SFormatNumber(C6) + " مليار"
End Select
If Letter6 <> "" And Letter5 <> "" Then Letter6 = Letter6 + " و" + Letter5
If Letter6 = "" Then Letter6 = Letter5
SFormatNumber = Letter6
