Summary:

When the system locale is set to he-IL (Hebrew, Israel), -[LengthFormatter stringFromMeters:] uses a different word to represent “meters” than what either -[LengthFormatter unitStringFromValue:unit:] or -[LengthFormatter unitStringFromValue:usedUnit:] returns. This is problematic, because -[LengthFormatter unitStringFromValue:unit:] is often used to find and format the unit differently than the rest of the length string in an attributed string.

Steps to Reproduce:

1. Set the system locale to Hebrew and the system region to a country that uses the metric system, such as Israel.
1. Call -[LengthFormatter stringFromMeters:] and -[LengthFormatter unitStringFromValue:unit:].

	let formatter = LengthFormatter()
	formatter.unitStyle = .medium // or .short
	print(formatter.string(fromMeters: 5))
	print(formatter.unitString(fromValue: 5, unit: .meter))
	print(formatter.unitString(fromMeters: 5, usedUnit: nil))

Expected Results:

5 מ׳
מ׳
מ׳

Actual Results:

5 מ׳
מטר
מטר

Notes:

Reproduces when the unit style is either short or medium, but not when the unit style is long. Reproduces when using meters but not when using feet.
