How to use directional arrows in TextView

What's the correct way to use directional arrows within a TextView without having to create a drawable? Unicode has been thought of but it's not clear which character codes need be used. What code must be used both for HTML and programmatically for the left, right, up & down arrows? Ideally to get the same result as the arrows used in the screenshots below (notice how they are correctly autosized and positioned in line as the text).

You are right you can use Unicode like below

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:orientation="vertical">


<androidx.appcompat.widget.AppCompatTextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:text="→ right" />


<androidx.appcompat.widget.AppCompatTextView
    android:id="@+id/textView2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:text="← left" />


<androidx.appcompat.widget.AppCompatTextView
    android:id="@+id/textView3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:text="↑ top" />

<androidx.appcompat.widget.AppCompatTextView
    android:id="@+id/textView4"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:text="↓ bottom" />
</LinearLayout>
