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

  • It's easier to help you if you include a simple [reproducible example](https://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example) with sample input and desired output that can be used to test and verify possible solutions. Usually I see the "ÿ" when you improperly read in a file with a byte-order marker that you do not account for. – MrFlick Dec 13 '22 at 15:44
