I find it strange that while the Armenian language (keyboard layouts and characters) is supported on OS X, on iOS it is not supported at all.
A jailbreak on iOS 3 allowed me to install iKeyEx from Cydia, which had an Armenian keyboard in it. This solution no longer works because the app is not supported. Besides, jailbreak probably isn't the answer. There are 3rd party apps (like iTetr) that can be used for typing in Armenian.
How can I get Armenian language support in iOS?
