I am trying to create a substitute() that will convert greek characters to latin.
The problem is that after declaring
Dim Source As String
Source = "αβγδεζηικλμνξοπρστθφω"
Source is interpreted as "áâãäåæçéêëìíîïðñóôõöù"
is there any way use unicode at declaration level?
To insert a Unicode character, type the character code, press ALT, and then press X. For example, to type a dollar symbol ($), type 0024, press ALT, and then press X. For more Unicode character codes, see Unicode character code charts by script.
VBA uses ANSI. So whenever doing any interaction with the OS VBA Unicode strings are converted to ANSI.
You use the Const statement to declare a constant and set its value. After a constant is declared, it cannot be modified or assigned a new value. You can declare a constant within a procedure or at the top of a module, in the Declarations section.
Description. The Microsoft Excel STRCONV function returns a string converted to uppercase, lowercase, proper case or Unicode. The STRCONV function is a built-in function in Excel that is categorized as a String/Text Function. It can be used as a VBA function (VBA) in Excel.
You can try StrConv
:
StrConv("αβγδεζηικλμνξοπρστθφω", vbUnicode)

[EDIT] Another solution:
You can get every greek character (lower and upper case) thanks to this procedure:
Sub x()
Dim i As Long
For i = 913 To 969
With Cells(i - 912, 1)
.Formula = "=dec2hex(" & i & ")"
.Offset(, 1).Value = ChrW$(i)
End With
Next i
End Sub
You can create an array to find the char for instance.

[EDIT 2] Here is a sub to build the string you wanted:
Sub greekAlpha()
Dim sAlpha As String
Dim lLetter As Long
For lLetter = &H3B1 To &H3C9
sAlpha = sAlpha & ChrW(lLetter)
Next
End Sub
As previously mentioned, VBA does support unicode strings, however you cannot write unicode strings inside your code, because the VBA editor only allows VBA files to be encoded in the 8-bit codepage Windows-1252
.
You can however convert a binary equivalent of the unicode string you wish to have:
str = StrConv("±²³´µ¶·¹º»¼½¾¿ÀÁÃĸÆÉ", vbFromUnicode)
'str value is now "αβγδεζηικλμνξοπρστθφω"
Use notepad to convert the string: copy-paste the unicode string, save the file as unicode (not utf-8) and open it as ASCII (which is in fact Windows-1252), then copy-paste it into the VBA editor without the first two characters (ÿþ), which is the BOM marker
You say that your source is interpreted as "áâãäåæçéêëìíîïðñóôõöù".
Note that the Visual Basic Editor doesn't display Unicode, but it does support manipulating Unicode strings:
Dim strValue As String
strValue = Range("A1").Value
Range("B1").Value = Mid(strValue, 3)
Range("C1").Value = StrReverse(strValue)
If A1 contains Greek characters, B1 and C1 will contain Greek characters too after running this code.
You just can't view the values properly in the Immediate window, or in a MsgBox.
