    Not at all. The numeral for ten is clearly NOT a LATIN CAPITAL LETTER
    T - rather, it's a symbol that has been designed to be reminiscent of
    but distinct from a T (compare it with the Ts on the same page);
    similarly the eleven symbol is a special sort that is like L but not
    the same. This is explained on page 15: (duodecimal), which since the
    OCR doesn't understand non-decimal page numbers is reached by going to
    (decimal) page 15 in the jump to page box.
    Of course, as it says, T and L can be used if you don't have the
    special sorts.
