Both %c and %lc produce the same trace output:
trace:msvcp90:MSVCP_basic_string_wchar_assign_cstr_len 0x32fc20 L"abc" 3
trace:msvcp90:MSVCP_basic_string_wchar_append_len_wchar 0x32fc20 0 z
trace:msvcp90:MSVCP_basic_string_wchar_append_len_wchar 0x32fc20 2 z
Should I send a patch with %c instead?
The "l" modifier most likely is ignored and will print correct result only for ASCII symbols.
