I usually create a new file by doing Ctrl+O, get OS's open dialog (don't have Ctrl-O go to smart open) and then navigate to a directory and then type the name of a file that doesn't exist yet.
This lets me create a new file. I've been doing it this way for many years with SE. I like doing it this way.
When I tried it today with 26.0.2.1 (Linux x64) I get this warning and I don't get to edit the new file in the editor:
Error opening file: Code page not installed or not valid: <full path to my 'new' file>
