43c7fbb1e7 Make MSVC compiler read the source code using utf-8 (Chun Kuan Lee)
f86a571edb tests: Add test case for std::ios_base::ate (Chun Kuan Lee)
a554cc901a Move boost/std fstream to fsbridge (Chun Kuan Lee)
86eb3b3f1a utils: Add fsbridge fstream function wrapper (Chun Kuan Lee)

Pull request description:

  If compiled with mingw, use glibc++ extension `stdio_filebuf` to open the file by `FILE*` instead of filename.

  In other condition, we can use boost::fstream.
