A function of loadOsm.py needs one parameter more using in Windows 10 in korean

[minhokim0201]

Hello.

When I run pyroutelib2 in my windows system there has some problem in parseOsmFile(self, filename).
After I change "with open(filename, "r") as f: " to "with open(filename, "r", encoding="utf8") as f:". it works well.

Thanks.
