+// UnsafeBytes converts a string into a byte slice without making a copy of the data.
+// This function is considered unsafe because it directly manipulates memory and does not
+// perform any checks on the string's contents. It should be used with caution.
+//
+// Parameters:
+//   - str: The input string to be converted into a byte slice.
+//
+// Returns:
+//
+//	A byte slice representation of the input string. The returned slice shares the same
+//	underlying data as the original string, so modifications to the byte slice may affect
+//	the original string and vice versa.

+	d := unsafe.StringData(str)
+	b := unsafe.Slice(d, len(str))
+
+	return b
