Another thing to note is that std::string should only be used for paths. For UTF-8 strings, we should use Glib::ustring, which has a character-based index operator instead of a byte-based one.

Hi,

It is good we are slowly moving to using std::string... but mixing it with char* can be tricky. In particular, I've seen several bugs recently when char* is a null pointer. You cannot initialize a std::string with a null pointer. You will get at run time:

terminate called after throwing an instance of 'std::logic_error' what(): basic_string::_S_construct null not valid

I don't know what "best practice" is but this seems to work:

std::string my_string = c_string ? c_string : "";

You can also not compare a std::string to a null pointer.
