Word document content into an email

Is there any way to get clean html from a word document in VB.net to make it the body of an email. I can get the html into the body of the email but any special characters(ie. bullets, hyphens) in the word document come out as odd characters in the html like squares and unknown shapes. The code I am using to get the html in the email is below. It works, but has unexpected characters in the html.

Public Function SendEmails(ByVal sEmailFrom As String, ByVal sEmailSubject As String, _
                            ByVal sSMTP As String, ByVal sTo As String, ByVal sCC As String(), _
                            ByVal sFileName As String) As Boolean
        Dim bResult As Boolean = True
        Dim oMessage As New MailMessage(sEmailFrom, sTo)
        Dim oSMTP As New SmtpClient
        oSMTP.Host = sSMTP
        oMessage.Subject = sEmailSubject
        For Each sCCAddress As String In sCC
            oMessage.CC.Add(sCCAddress)
        Next
        oMessage.IsBodyHtml = True
        oMessage.Body = GetWordContent(sFileName)
        Try
            oSMTP.Send(oMessage)
        Catch ex As Exception
            MsgBox(ex.Message)
            bResult = False
        End Try
 
        Return bResult
    End Function
 
Private Function GetWordContent(ByVal sFileName As String) As String
        Dim sResult As String = String.Empty
        Try
            Dim oStream As StreamReader
            oStream = File.OpenText(sFileName)
            sResult = oStream.ReadToEnd
        Catch ex As Exception
        End Try
        Return sResult
    End Function
