Chris,

If I understand your question correctly you are asking for a way to decode encoded HTML?  If so, you can decode any encoded text in the Script activity with a single line of code using the HTMLDecode method on the System.Net.WebUtility class.

Here is some sample code that takes an encoded text string from a token named EncodedHTML and correctly decodes it to a token named DecodedHTML.  The script correctly decodes both examples you cite.

Imports System
Imports System.Collections.Generic
Imports System.ComponentModel
Imports System.Data
Imports System.Data.SqlClient
Imports System.Text
Imports System.Net

Namespace WorkflowActivity.Scripting.Script
    '''<summary>
    '''Provides one or more methods that can be run when the workflow scripting activity is performed.
    '''</summary>
    Public Class Script1
        Inherits ScriptClass90
        '''<summary>
        '''This method is run when the activity is performed.
        '''</summary>
        Protected Overrides Sub Execute()

            Me.SetTokenValue("DecodedHTML", System.Net.WebUtility.HtmlDecode(Me.GetTokenValue("EncodedHTML")))

        End Sub
    End Class
End Namespace
