# Why latex file shows some characters instead of digits?

I wrote a text in overleaf and then i transferred the file to winedit. But, some digits and characters are shown wrongly with some symbols.

Formula in overleaf vs formula transferred in winedit

• Welcome to TeX.SE! PLease show us a code for equation (as part of complete small document beginning with \documentclass and ending with \end{document}. – Zarko Jan 31 at 7:30
• Maybe you transfer the formula to winedit, but not the preamble of the document? – Fran Feb 2 at 5:34
