D doesn't read the first character of a file (reads everything but the first chararacter) with either read() or readText()

I'm feeling this. My keyboard sometimes messes up and will send 
invalid key presses to my OS which often ends up with invalid 
characters being written in files.

When I encounter it I usually open Notepad++ and turn on show all 
characters which will display unprintable characters, simply 
allowing me to delete them and have a clean file again.
