+# We are assuming that:
+# * Most fonts that claim to support an Arabic letter actually do so;
+# * Most modern text rendering software use OpenType tables, instead of
+#   directly using presentation forms.
+# * Some good Arabic fonts do not support codepoints for Arabic presentation
+#   forms.
+# Thus, we are switching to general forms of Arabic letters.
