Encoding Problems

Sometimes we have trouble handling strange characters that must be transferred from one page to another. In general, should we have the habit of transferring strings using encode. In ASP.Net we do so like this:

strLink = "ShipDatePopup.aspx?BypassUser=&" & strGlobalUser & "&Inco2=" & Server.UrlEncode(txtIncoterm2.Text

To Recover this value, we do not need to do anything special just:
txtIncoterm2.Text = Request.QueryString("Inco2")
