Thanks for clearing that up.  The reference to Appendix D of the C99 spec threw me, as it referred to these characters.  I suppose I should have realized that you meant the letters themselves rather than the formatting.

Me either.  I stumbled across that portion of the spec yesterday and tried it on a whim :-)  Sorry for the confusion.

I have come across them in obfuscated C code :-)
