Parse non-ascii string from argv in 'main' function C++

Question

I am writing a console program that processes files passed by the user as launch arguments (reads, processes in a certain way, writes to other files). The problem is that file paths can contain chinese, german, ukrainian and other non-standard letters, which are incorrectly processed by the program (impossible to open files due to an incorrect path). I can use 'wmain' and 'wchar_t** argv' instead of 'main' and 'char** argv', but I haven't seen any library for argument parsing that supports wchar_t argv, and I, besides paths, have to parse many more parameters of different types.

Tell me, please:

1. Is it possible to get by with exclusively ordinary char when processing paths containing non-ascii characters?
2. Do you know any argument parsing libraries that support 'wmain'? (most popular, 'argparse', doesn`t support it.)

• john: Regarding #1 you cannot do anything at all until you know what encoding your non-ASCII characters are represented by. This crucial information is missing from the description above. Do you know the encoding?
• Paulo1205: Dou you mean replacements for strcmp(), strlen(), and such? Don't wcscmp(), wcslen() and related (in <wchar.h>, or <cwchar> in C++) work for you?
• Chase: @Paulo1205 no, I don't mean that. I described exactly what the problem is: I either can’t parse the rest of the arguments (since there is no parsing library that supports wmain), or I can’t get paths from argv if they contain non-ascii characters
• Paulo1205: @Chase, if you cannot find a library, you can make your own with the building blocks I suggested. Also, you can probably get at least a little further with regular char-based libraries if you properly configure locale in your program, but YMMV. Finally, with a simple Google, I found about a version of getopt that was ported to Unicode (codeproject.com/Articles/157001/…) Would that work for you?
• n. m. could be an AI: boost::program_options support wchar_t. Googling "wchar_t getopt" returns quite a bit of results too.
