I need to (among other tasks) un-encode some substitutions in a string that use URL-encoding. That is, locate all occurrences of "%nn" and replace with the character whose ordinal is 0xnn. I looked at boost/algorithm/string.hpp, but the instructions are not at all clear. The tutorial/example is too simple, and the reference it points to for more info is quite unenlightening. Could someone show me how to do that, or point to an example that's more along those lines?
