[Boost-users] [concept_check] Why does char not qualify as "Integer"?

The statement

BOOST_CONCEPT_ASSERT((boost::Integer<T>));

triggers an error if T is the type char. It does not trigger an error if T 
is either of type signed char or unsigned char.

I can understand why it's not so easy to detect for SignedInteger or 
UnsignedInteger given type char, but to my understanding using type char 
should work with the above statement.
