Suppose my basic_string<wchar_t, char_traits<wchar_t>, allocator<wchar_t> > contains the string "abc". And when I printed it out in the --trace mode using the %{#*S} directive I have got "a\0b", but "abc" (or "a\0b\0c\0" if each byte is printed) was expected. Is this correct?
No, that would not be correct. If there are no NULs in the string the directive certainly shouldn't print any. Can you put together a small test case? (The little program I copied in my previous response behaved correctly.) Martin
