any brute force attack will use a dictonary based on know passwords and the usage frequency, if people are unlikely to use "accented letters" in their passwords it increase the time taken to bruteforce
Dunno why people are down voting you. Password lists have been around since forever, and anybody trying to brute force will start with one. Why cycle through "A", "AA", "AAA", "AAAA", etc first when you're far more likely to score a hit faster with a list?
No. No human is trying trillions of combination to brute force an attack. A machine does it, the machine will try all symbols and lettera.
