Run-time error '5' VBA when running against specific PDF

I have the following Code in VBA following an answer to my last question, which iterates over a list of URLs and generates a text file using the word to extract the text.

For the following URL however; https://hpvchemicals.oecd.org/ui/handler.axd?id=97a7b56f-ebaf-4416-8b4b-88b19ca3bd16, the code fails with Run-time error '5' Invalid procedure call or argument.

Whats strange is the text of the PDF prints to the console but wont write to the text file.

I can't quite understand why this happens as the PDF appears to be no different to the others, which are successful.

VBA Code: requires Microsoft Scripting Runtime reference

Sub Tester()

    Dim filePath As String
    Dim fso As FileSystemObject
    Set fso = New FileSystemObject
    Dim fileStream As TextStream
    
    Dim oWd As Object, oDoc As Object, c As Range
    
    Set oWd = CreateObject("word.application")
    
    n = 1
    
    For Each c In Range("B2:B200").Cells
    
    filePath = Range("D2").Value & "\" & Range("A" & n).Value & ".txt"
    
    Debug.Print filePath
    
    Set fileStream = fso.CreateTextFile(filePath)
   
    Debug.Print c.Value
        
        With oWd.Documents.Open(c.Value)

            Debug.Print .Range.Text
            'write to a file...
            fileStream.WriteLine .Range.Text
            fileStream.Close
            
        End With
        
        n = n + 1
        
    Next c
    
    oWd.Quit
    
End Sub

So firstly, I think it's likely that the issue with the last URL can be solved. However, I think I also need to introduce some error handling that generates a blank text file and moves on to the next but im not sure how to achieve this.

I am not very competent with VBA, I have specified to repeat for rows B2:B200, but ideally, it would be good if, regardless of how many URLs, it just works to that number.

Also not sure if the logic in my code is particularly robust/if there is a better way to extract text from a URL.

The expected output is:

And here is an example of the generated Text file.

Seems like the document returned from that problem URL contained some characters which couldn't be written to a non-unicode text file.
