declaring a unicode string in vba in excel [duplicate]

This question already has answers here: How to type Unicode currency character in Visual Basic Editor (2 answers) Clo开发者_运维百科sed 3 years ago.

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?

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.
