On our Philips Electrologica X1 with 5-channel paper tape, there was
*no* single character to mark a file (tape) end, but the end consisted
of a high number (at least 20) of all 5 rows punched. This is no
printable character, but the switch code from the cipher part of the
code to the letter part (on 5-channel tape, you have 26 chars being
ambiguous, letters in letter mode or digits or other mathematical
signs in cipher mode, else you wouldn't get enough codes).

Later on our ICL mainframe, a line consisting of 4 asterisks (****)
normally served as an end of file delimiter.
