Len and LenB

Now, in the MSDN, Len is supposed to return the length of the string, and LenB is supposed to return the length of the string in bytes, right?

But when I ran this:

Code:

---

Private Sub Form_Load()

Dim header As String

header = Space(8)
MsgBox Len(header)    'an answer of 8
MsgBox LenB(header)    'answer of 16 (?)
header = "12345678"
MsgBox header          'answer "12345678"
MsgBox Len(header)    '8
MsgBox LenB(header)    '16

'the file contains the character "1" in it
MsgBox FileLen("c:\windows\desktop\test.txt")  'answer of 1
msgbox LenB("1") 'answer of 2!!
End Sub

---

Why does LenB say that "1" uses 2 bytes? It seems that one character always takes up 2 bytes, but FileLen reports a file with the same character as 1 byte. Why is this so?

Thanks

LenB returns the number of bytes used to represent the string (two per character), while FileLen returns the actial number of bytes in a file
