That's true: an extra complication! However, I have only seen that for one- or two-digit numbers. This is also used for single letters or two-letter acronyms (such as "Km"). Probably this is the reason for the "squared letters" in range U+3380..U+33DD (some of which are 3-letter long, BTW). But that would a limited case for horizontal text embedded in vertical text: I cannot imagine a real-world situation for a vertical text embedded in horizontal text. _ Marco
