Summary:
This is an "us, too" report for rdar://29182929 where the keystroke function is incorrectly casing of output to uppercase based on uppercase and other sentinel characters. We've also identified a work-around that we haven't seen reported, described in Additional Notes.

Steps to Reproduce:
1. Open Script Editor
2. Either open the attached sample script or paste this:
tell application "Terminal"
	activate
	tell application "System Events" to keystroke "This is a test"
end tell
3. Watch the output in Terminal.app

Expected Results:
The script should properly print each entered character in the correct casing.

Actual Results:
The casing is different from what was entered and differs with almost every run.

Version:
macOS Sierra 10.12.2 (16C67)

Notes:
This is our work-around, forcing an adjustment to shift after using keystroke to emit each character individually:

tell application "Terminal"
	activate
	tell application "System Events"
		set outputString to "mmalibu@zetetic.net"
		set len to length of outputString
		repeat with i from 1 to len
			set x to character i of outputString
			keystroke x
			key up {shift}
		end repeat
	end tell
end tell

I should note that the problem appears to remain in 10.12.3 Beta 2.

Configuration:
The output is occasionally correct, but the frequency varies quite a bit.
