If a Latin initialism
A what?
appears in a bottom-to-top text and the characters are oriented upright rather than rotated, should the initialism read up or down?
U A S or S ? A U
In addition to the anachronism in this particular example, what you've said doesn't make sense. In Ogham, you'd write (using feather marks here) >-U-S-A-< and in bottom to top orientation that whole string would be rotated with the U toward the bottom and the A toward the top.
What you described would just be wrong. -- Michael Everson * * Everson Typography * * http://www.evertype.com
