I´ve made a function that return an accent a (á) but when I call it, returns another value.

Public Shared Function x1() As String
Return “á”
End Function

Public Shared Function x2() As String
Dim oConDB As New DoConexionOracle(Constants.STRCON)
Return oConDB.ObtenerEscalarFromSQL(“select ‘á’ FROM DUAL”)
End Function

SELECT x1() FROM DUAL
á

SELECT x2() FROM DUAL
á

Any idea?
TIA,
Christian
