Why not use Windows Notepad?
Windows Notepad is not necessarily helpful here, it can add in some additional characters or leave out some other characters and that do not sit well inside some versions of Moodle. Windows’ Notepad does not save files using the UTF-8 charset, which is required for Moodle. Well, Moodle saves files in the database as a UTF-8 format, Moodle PHP files are written, then saved in the UTF-8 format, so it is easier to setup and use a text editor that can do the same. The UTF-8 format uses a larger range of characters than the ASCII charset that Notepad does.
