I actually spent yesterday trying to figure out why my XML writing code was all messed up. <color red=" Took me a while to figure that one out. On 7/18/06, Philipp Henkel <threadpool@googlemail.com> wrote:

Dear all,

I wondered about boost::format's printf behaviour regarding char's. There seems to be no difference between the two format pattern "%c" and "%d". boost::format does not interpret chars as decimal values when using "%d".

Please take a look a the following example:

unsigned char foo = 65; printf("foo = %d", foo); // output is "foo = 65"

std::string bar = (boost::format("foo = %d\n") % foo).str(); printf(bar.c_str()); // output is "foo = A" which is what I want when using "%c"

Is this behaviour intended? From my point of view it's dangerous because printf users do not expect it. Furthermore it may lead to string truncations because of string terminators (char is 0) which are inserted by accident.

Did I overlook something?

I'm using boost 1.33.1 / VC8.
