I am trying to create a keyboard in my native language where some characters are formed by combination of other characters. Here is the code snippet that I have tried

<Key
        android:codes="0x91C,0x094D,0x091E"
        android:keyLabel="ज्ञ" />
    <Key
        android:codes="0x915,0x094D,0x937"
        android:keyLabel="क्ष" />
    <Key
        android:codes="0x936,0x094D,0x930"
        android:keyLabel="श्र" />

In the first example 0x91C = ज,0x094D = ् ,0x091E = ञ; I tried with + between Unicode’s, and without having any as well. Is there any correct syntax or code I need to update here. It is in UTF8 format.
