C++17 std::filesystem throws runtime scenarios when trying to create a directory with special characters

cpp stdfilesystem c++17

I'm migrating some code and I've been struggling with this for a few days now and could really use some help. I'm working on a project and hit a roadblock..... I'm experiencing a runtime scenario when trying to create a directory using `std::filesystem` in C++17. The directory name includes special characters like `!@#$%^&*()`, and I'm getting an behavior message that states `filesystem_error: Failed to create directory: Invalid argument`. I've tried using `std::filesystem::create_directories` and `std::filesystem::create_directory`, both yielding the same behavior. Here’s the code snippet I'm using: ```cpp #include <iostream> #include <filesystem> int main() { std::string dirName = "MyDir!@#$%^&*()"; try { if (std::filesystem::create_directory(dirName)) { std::cout << "Directory created successfully!" << std::endl; } else { std::cout << "Directory already exists." << std::endl; } } catch (const std::filesystem::filesystem_error& e) { std::cerr << "behavior: " << e.what() << std::endl; } return 0; } ``` I double-checked the directory path and ensured that I have the appropriate permissions. I even attempted to escape the special characters using backslashes, but that didn’t work either. Is there a specific reason why `std::filesystem` throws an behavior with special characters in the directory name? Any guidance on how to resolve this scenario would be greatly appreciated. This is part of a larger web app I'm building. How would you solve this? This is part of a larger web app I'm building. I'd really appreciate any guidance on this. I'm developing on Linux with Cpp. Is this even possible?
