What is the default Meta key for Irssi (IRC) in Terminal?
I noticed that I can use the ⌥ Option key as Meta key if enabled in Terminal settings, but this prevents me from using it to type special characters.
If there is no default Meta key, is it possible to define one different from ⌥ Option?
And, as I already answered you on stackoverflow, the solution is to put the following line into your ~/.bash_profile, which remaps the unicode character "∫" (Unicode: E288AB, which is what is sent to your terminal right now in your desired configuration when you press Option + °) to the backslash character:
bind '"\033\xE2\x88\xAB"':'"\\"'
There's probably a better way to do this, but you could try saving this as private.xml in KeyRemap4MacBook:

This wouldn't work with repeated key presses:
__KeyToKey__ KeyCode::OPTION_L, KeyCode::VK_NONE, Option::KEYTOKEY_BEFORE_KEYDOWN, KeyCode::ESCAPE

According to Irssi documentation, it's Alt, which I believe the author meant ⌥ Option to be on macOS, as this is how ⌥ Option is usually used on macOS compared to Windows.
However, on macOS Mojave, it is actually Esc.
