fix: fix utf-8 output error.

- 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.
