+In text examples, the subsection title (bold) sometimes shows the wire order,
+transcribed to English (“Shalom” abbreviated to occupy the same width).
+This is followed by the reference rendering, using similar LTR glyphs.
+Finally the actual rendering which should match the line above.
+
+All words, except for subsection titles under explicit modes, should show up
+in human readable order.
+
+Boxes should all show up nicely.
