This does not seem so unreasonable. The RTL and LTR overrides *function* on the text when inserted into text. So you can't use those with glyphs in a font to represent for example the UCS dotted-boxes-with-letters, because they are control characters and will affect the text. > I don't think there's any end to where this can go.

I do not follow the logic of this assertion. SPACE and SYMBOL FOR SPACE exist. No infinite recursion is needed. Michael Everson * http://www.evertype.com/
