	Save the current file with encoding UTF8, then close.

	To trigger the command with 'Command Option Shift 8',
	add the following to your Sublime Text > Preferences > Keybindings - User

	[
	    { "keys": ["super+option+shift+8"], "command": "save_as_utf8"}
	]
'''

class SaveAsUtf8Command(sublime_plugin.WindowCommand):
    def run(self):
        self.window.run_command("save", {"encoding": "utf-8" })
        self.window.run_command("close")

It doesn't work as a macro; maybe these commands are out of scope for a macro (eg a window command not a view command?).

[
    { "command": "save", "args": {"encoding": "utf-8" } },
    { "command": "close", "args": null }
]

Looks like it might work, but produces:

Unknown macro command save
Unknown macro command close

in the console
