Is it still necessary to use packages T1 and utf8 in editor TeXstudio?

Question

I have an old TEX file where we used
usepackage[T1]{fontenc}
usepackage[utf8]{inputenc}

I figured out form here that T1 is needed for  |, < and >.
But do I still need utf8? I am on windows, I use TeXstudio and it seems, I don't need it - all Umlaute are displayed correctly.

A short writeup of the comments

if you use pdflatex T1 with fontenc is still relevant for better use of the fonts.
as for utf8 it is now the default has has been for some time, so you ought to be able to drop it. Personally I tend to add it anyways just as a reminder (some editors actually scans the preamble) but also if the document later on might be sent to others where you don't know if they are using an older latex installation (that might for example be arXiv).
