 Hi.

 I was disappointed to learn that Boost::format will print an unsigned char
 as a character despite the format string being set to an integer. This is
 different then the behavior of printf, and goes against intuition as I
 explicitly specified the datatype.

 unsigned char smallnumber = 4;
 printf("%d",smallnumber);%good
 boost::format("%d") % smallnumber; // bad, treats as  char, outputs
 strange character

 It looks I'm not the only one that had this problem:

 Wanted to make sure the boost people knew about this,
