Add "Notes on the execution environment language" to README.md

[junkmd]

Replacing "Simple Example" with the following will help clarify any misconceptions about this package.

Simple Example

It is simple and the resulting scripts are very readable. How simple?

from pywinauto.application import Application
app = Application().start("notepad.exe")

app.UntitledNotepad.menu_select("Help->About Notepad")
app.AboutNotepad.OK.click()
app.UntitledNotepad.Edit.type_keys("pywinauto Works!", with_spaces=True)

Notes on the execution environment language

In environments where the interface language is not English, the above script may not work correctly.

For example, in Japanese, you need to do the following:

from pywinauto.application import Application
app = Application().start("notepad.exe")

app.UntitledNotepad.menu_select("ヘルプ->バージョン情報")
app.バージョン情報.OK.click()
app.UntitledNotepad.Edit.type_keys("pywinauto Works!", with_spaces=True)

Any opinions would be appreciated.
