I made a class that fetches text in a .TXT file that is saved in UTF-8 format, and write to the Clipboard so I can paste it with CRTL + V into a field on another system. The problem is that when I use CRTL + V a ? appears before the text. In some other places, if I use CRTL + V it glues right, but in the field I actually need to paste, it appears this ? before. Example, if the TXT contains "Hello World!" and I run the class and give CRTL + V it will paste " ?Olá Mundo! ". I searched a lot and in notepad++ I found that if I paste something there and go to the "Code for ANSI" option it puts this ? before the text, but I do not understand how to solve it in my% code%.
