German speaking countries
When you wish someone good luck in German you would say "Ich drücke dir die Daumen", which literally means "I'll press my thumbs for you". Because of that, 🤞 ("I'll keep my fingers crossed") isn't used to wish good luck (in German 🤞 means that you are lying). We rather use ✊ which stands for the thumbs pressed.
"Viel Glück bei der Prüfung! Ich drücke dir die Daumen ✊!"
"Good luck for the exam! I'll press my thumbs for you ✊!"
