Support file names with Unicode characters (e.g. CJKV, etc)

The fix might need to be different on Windows and Linux due to different native encoding (UTF-16 vs UTF-8).

Problem	Problem's essence	How to fix
Linter's output source encoding is lost if Cpp-lint-combine using in Visual Studio in "explicit mode"	Source encoding is lost because linter's output go through the chain of conversions: UTF-8 -> CP437 (Visual Studio console encoding) -> UTF-8	We must try to convert all possible characters in the linters output from UTF-8 to CP437. We can convert character from UTF-8 to CP437 only if this character contains in CP437 characters set
Cpp-lint-combine can't read command line arguments with Unicode characters on Windows	On Windows, if we use usual main() and usual type for argv we can't read Unicode characters from the command line, because we are received command line arguments not in UTF-8 encoding	We must read command line arguments by another way e.g. - use wmain() instead main()
Clazy exits with error if path of file to analyze contains Unicode characters	Clazy like Cpp-lint-combine reads command line arguments using usual main() and usual type for argv, so Clazy can't read Unicode characters from the command line, because Clazy is received command line arguments not in UTF-8 encoding	We can try to convert Clazy command line into UTF-8 in Cpp-lint-combine
