I have been trying to run STM, but the results show a full column with "ÿ" as a topic. My text documents do not have this special character and I am not able to get rid of it. Please advise why the Topic 1, has these characters showing up ?
Below is my STM results
Topic 1: ÿ, 8ÿ, 9ÿ, ÿÿ, 5ÿ
Topic 2: work, financi, new, payment, note
Topic 3: inflat, price, monetari, target, expect
Topic 4: financi, risk, monetari, stabil, crisi
Topic 5: growth, trade, export, product, econom
