hi i wanna crate custom keyboard in android.
i wanna use this code
http://code.tutsplus.com/tutorials/create-a-custom-keyboard-on-android--cms-22615[^]

but now i wanna make Arabic keyboard but i have problem with that because Arabic ASCII code is two part and the XML doesn't support that
i use this site to convert: http://www.asciitohex.com/[^]

for example 'ش' code is '216 180' but i can't use that in this XML:

<Row>
		<Key android:codes= "216 180" android:keyLabel="ش" android:keyEdgeFlags="left"/>
		<Key android:codes="115" android:keyLabel="س"/>
		<Key android:codes="100" android:keyLabel="ی"/>
		<Key android:codes="102" android:keyLabel="ک"/>
		<Key android:codes="103" android:keyLabel="ژ"/>
		<Key android:codes="104" android:keyLabel="ن"/>
		<Key android:codes="106" android:keyLabel="ت"/>
		<Key android:codes="107" android:keyLabel="ا"/>
		<Key android:codes="108" android:keyLabel="ل"/>
		<Key android:codes="35,64" android:keyLabel="\# \@" android:keyEdgeFlags="right"/>
	</Row>
