Hmm, I remember having this problem as well! I think it has something to do with the fact that Strings in .NET use the unicode character set (each character is two bytes, not one).

I'll go find a work around!

Yep, .NET utilizes the unicode character set. You can use the UnicodeEncoding class for all unicode manipulation:

    byte[] bytes = new System.Text.UnicodeEncoding().GetBytes(value);

Hmm it didn´t work for me, my function looks like this

 
Public Function SendText(ByVal sValue As String, ByVal sRemoteHost As String)
Dim MyByte As Byte()
 
        MyByte = New System.Text.UnicodeEncoding().GetBytes(sValue)

        MySocket.Send(MyByte, MyByte.Length, sRemoteHost)

    End Function

With this code "ÿ" will be a "square" and "å" will be "e"

I hav forgot to change to unicode in the recive function!

Tanks for all help
