After some searching, I found a
grep command that will find words containing capital letters, and list them without duplicates:
grep -hoP "\w*[[:upper:]]+\w*" * | sort -u
However, when it comes to words that contain characters such as
ê, it seems that grep returns the word only up to that character, ignoring the character and anything afterward. My text is encoded as
UTF-8, and I'm guessing the problem lies in my search criteria.
Is there a simple solution, for one who knows next to nothing about
