Don't you love little websites that do exactly what you need? (UTF-8 to/from cstr)

I use c# but asked chatgpt to convert my code to c++. To get the encoded you could use something like this.
#include #include #include std::string Encrypt(const std::string& input) {
std::string result;
std::ostringstream oss;for (char c : input) { oss << "\\\\#" << std::setw(2) << std::setfill('0') << std::hex << std::uppercase << (int)c; } result = oss.str(); return result;}
To Decrypt back you can use
#include #include std::string Decrypt(const std::string& input) {
std::string result;for (size\_t i = 0; i < input.length(); i += 4) { // Extract the two hexadecimal characters (skip the \\#) std::string temp = input.substr(i + 2, 2); // Convert the hex string to an integer int num = std::stoi(temp, nullptr, 16); // Convert the integer to a character and append to the result result += static\_cast(num); } return result;}
Let me know if this helps.

It doesn't, because I know how to do that. It's more effort to build that, or even to just launch a terminal window in order to run that vs navigate to that website and type in a string. Was actually using it to test UTF-8 -> UTF-32 conversion in my graphics lib - that does NOT use the C++ runtimes or The STL because embedded.

Also looking at that code, it doesn't do what the website does at all. It has no conception of UTF encoding. Pro-tip: (This one's free) - Don't ask GPT for help with code.
