I have code like the following

flags->add_option("--name", name_, "The name.")->required();

I want to be able to pass strings like "aa$p$aa" to the --name parameter. However, this does not seem to work with CLI11, and the name gets truncated to just "aa". I need to escape the $ characters to properly read the strings. So aa\$p\$aa works fine, and I get the expected string ("aa$p$aa").

Changing the function to add_flag() does not work either.

Is there a way to be able to pass arbitrary strings to a parameter as with either function calls above?

Your operating system takes the command you type in and executes the given program, passing the parameters to it.

The interpolation, and the handling of $ characters in typed-in commands is handled by your operating system as part of executing the typed-in command. Your compiled C program receives the transformed arguments, as parameters. Your C program has no means to control what has happened before it was even executed.
