How to avoid showing characters like Ä in android keyboard

Question

I am stuck in an issue where one of my user entering characters like Ä in an edittext and I am preparing an XML from that data. Due to encoding issue I can't prepare a valid XML from these kind of characters. Is there anyway I can stop user to enter such kind of characters or can I hide these characters from android default keyboard itself ?

Regards

you can restrict the user to enter only specific characters in the edit text like below,

<EditText
    android:id="@+id/YourEdittextId"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="textNoSuggestions"
    android:privateImeOptions="nm"
    android:digits="0123456789 abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ" />

Above code restrict user to enter only English digits, letters and space
