Title: Modified hex_char_to_int function

at boost/algorithm/hex.hpp, hex_char_to_int function

alphabet character sequence is a implementation defined.
not guaranteed by a standard that 'A' is less than 'F'.

and hex_char_to_int is not returned int. it returned unsigned despite this function name.
You might want to change a returning type unsigned to int or template T.

thanks for read this.
