Thanks for the great article. It was really helpful.

As you might know, the modified Punycode is just Punycode with upper-case letters instead of digits. See implementation here: https://gist.github.com/xtravar/6b52f59fb133229b360e

In C++, when defining a function, we can use the extern "C" attribute to force the C style mangling, which makes the function callable from a C code (and maybe also change the ABI in use). Is there anything similar in Swift? Something similar to @objc but making a simple swift function callable from C?

I found a way, mangle a known class and extract the target name using regex "_TtC[0-9]+([^0-9]+)[0-9]+". Then use that to generate mangled class names for any other class at runtime.

Do you know how to use the native Punycode converter? Let's say I have a ViewController, my app name is "Acá Estoy" and I want to generate the mangled name "_TtC10Aca__Estoy14ViewController".
I see that the Punycoding is adding an extra underscore for the acute "á", however I don't know how to generate this programatically.

Good article. Even first several paragraphs revealed things for me that I have never thought of. Like the fact that in objective-c you cannot overload methods, since you won't explore while doing regular stuff.

Great set of articles! I don't get into the guts of things as much as I used to...my code doesn't need to be blazing fast, but understanding stuff underneath never hurts. Fascinating and I enjoy following along.
