If I make text file with nothing in it and then after look at the text file with the following macro ..._

' A virgin text file
Sub AVirginTextFile()
' 1    Make a virgin text file
Dim FileNum2 As Long: Let FileNum2 = FreeFile(0)                                  ' https://msdn.microsoft.com/en-us/vba/language-reference-vba/articles/freefile-function
Dim PathAndFileName2 As String
 Let PathAndFileName2 = ThisWorkbook.Path & "\" & "NoText.txt"  ' CHANGE path TO SUIT
 Open PathAndFileName2 For Output As #FileNum2
Dim NoText As String
 Print #FileNum2, NoText ' write out entire text file, the file is made if not there
 Close #FileNum2
' 2a)  Get the text file as a long single string
Dim FileNum As Long: Let FileNum = FreeFile(1)                                    ' https://msdn.microsoft.com/en-us/vba/language-reference-vba/articles/freefile-function
Dim PathAndFileName As String, TotalFile As String
 Let PathAndFileName = ThisWorkbook.Path & Application.PathSeparator & "NoText.txt"   '                                                               CHANGE TO SUIT                                                                                                         From vixer zyxw1234  : http://www.eileenslounge.com/viewtopic.php?f=30&t=34629     DF.txt https://app.box.com/s/gw941dh9v8sqhvzin3lo9rfc67fjsbic
Open PathAndFileName For Binary As #FileNum 'Open Route to data. Binary is a fundamental type data input...
 Let TotalFile = Space(LOF(FileNum)) '....and wot receives it has to be a string of exactly the right length
Get #FileNum, , TotalFile                                               'Debug.Print TotalFile
Close #FileNum
 Call WtchaGot_Unic_NotMuchIfYaChoppedItOff(TotalFile)
End Sub

_... then I will see nothing at all in Notepad, and from my WotchaGot function it will tell me that I have
vbCr & vbLf

If I Let NoText = "x" , and repeat the experiment, I see in notepad .._

x

_.. and my function tells me that I have
"x" & vbCr & vbLf

Here are some more experiments, and the results:
Let NoText = "x" & vbCr & "x"
"x" & vbCr & "x" & vbCr & vbLf

xx

Let NoText = "x" & vbLf & "x"
"x" & vbLf & "x" & vbCr & vbLf

xx

Let NoText = "x" & vbCr & vbLf & "x"
"x" & vbCr & vbLf & "x" & vbCr & vbLf

x
x

Let NoText = "x" & vbLf & vbCr & "x"
"x" & vbLf & vbCr & "x" & vbCr & vbLf

xx

If I repeat the experiment using extension .csv instead of .txt everywhere in my macro, then the results are identical.
So it appears that notepad only recognises the pair vbCr & vbLf as a new line

( Note: if I open any of the files ( .txt or .csv ) in Excel , using any default settings, then for the case of the vbLf or the vbCr or the pair vbCr & vbLf then Excel always seems to add a line and I see
_____ Workbook: NoText.txt ( Using Excel 2007 32 bit )

Row\Col	A
1	x
2	x

Worksheet: NoText
_____ Workbook: NoText.csv ( Using Excel 2007 32 bit )

Row\Col	A
1	x
2	x

Worksheet: NoText

For the case of using vbLf & vbCr, using the default settings opening in Excel the .txt file also gives the same result, but strangely for the .csv file we see an extra line
