I was wondering how Windows interprets characters.

I made a file with a hex editor with the 3 bytes E3 81 81.
Those bytes are the ぁ character in UTF-8.

I opened the notepad and it displayed ぁ. I didn't specify the encoding of the file, I just created the bytes and the notepad interpreted it correctly.

Is notepad somehow guessing the encoding?
Or is the hex editor saving those bytes with a specific encoding?

windows encoding utf-8 notepad hex-editors
