- update the implementation of ParserHelper from locale-based std::to_string, std::stod, std::stoull, to locale-independent function std::from_chars and std::to_chars.
- rename TerminalHelper to ConsoleHelper.
- I figure out how UTF-8 output bug happend, but I don't have any clues proving why this happend.
- it seems that we can simply remove utf8 string literal heading to solve this issue (u8"" -> "")
- the compiled string char array in executable application already is wrong.
- compiler generated string bytes is `'original string'.encode('utf-8').decode(your pc encoding).encode('utf-8')`.
- idk why, as the compromise, I remove all utf8 string literal heading to solve this issue.
- I highly think this is a bug of MSVC. because everything is okey if I use MSVC native project file to build.
- I have compared the build flags between native project and cmake generated project but I can't find any difference.
- add full testbench code for ParserHelper.
