OK, the code is here: http://svn.chezphil.org/libpbe/trunk/include/charset/

Another conceptual problem in your traits. Take a look at UTF-8's skip_forward_char: template <typename char8_ptr_t> static void skip_forward_char(char8_ptr_t& i) { do { ++i; } while (!char_start_byte(*i)); // Maybe hint this? } And this loop: for(iterator it = cnt.begin(); it != cnt.end(); skip_forward_char(it)) { } This will always invoke undefined behaviour. Consider the case where it is just before end(), i.e. ++it == cnt.end(). Then skip_forward_char() will indeed do ++it, and then do *it, thus dereferencing the past-the-end iterator. Boom. Compare with filter_iterator. skip_forward_char *must* take the end iterator, too, and stop when reaching it. This, in turn, makes the charset adapter iterator that much more complicated.
