I’ve made a program for school; that goes through a plain text file and makes a concordance for each word. It will take each word, remove non-alphabetical characters from the front and back, and put it into a Binary Search Tree. When encountering Unicode characters in a text, you get random ascii characters that make up the multibyte character instead of what it is: for example, yarns—and is outputted as yarnsùand. I spent hours months ago and this week trying to solve this problem, so what do I do?
