Hi ! I'm using the Date_Time library on Windows. The "tz_database" has only one method to populate it with the data from "date_time_zonespec.csv" file. It is "load_from_file" method which takes a filename in std::string. I wonder if it's possible to overload that method so it could be more generic (and much more useful). It could take for example a reference to std::istream object. The idea is to avoid to save the data in a .csv file on a disk. I could then put the data in the resources of an .exe or .dll file, create some stream object derived from std::istream and load into the "tz_database" object. The second limitation of the existing version of "load_from_file" is that I can't use unicode string to provide the filename. What the Developers think about such small addition ?
