In Haskell the character U+FFFD can be written thus (inside character
or string literal):
\65533
\xFFFD
\o177775
Such escape sequences can have any number of digits. The sequence \&
expands to the empty string and is used to protect a sequence from
the following text if it begins with a digit.

This conflicts with the usage of \v as vertical tab.
