Docx - Notepad-Chinese characters

Just recently I had to have a drive replaced and windows 11 was installed. Ever since then whenever I create a Word document, which is now the docx format, I have to open it on notepad. The problem is Notepad only opens with Chinese characters. This happens with any Word document. Does anyone know why tis has started happening and is their a fix? It did not happen with my previous Windows 11 installation. Thank you
