1. Hex FF (11111111) when used as a delimiter or {fence} character.
Usage: primarily at IBM shops.
2. [proposed] n. The Unicode non-character U+FFFF (1111111111111111),
a character code which is not assigned to any character, and so is
usable as end-of-string. (Unicode is a 16-bit character code intended
to cover all of the world's writing systems, including Latin, Greek,
Cyrillic, Chinese, hiragana, katakana, Devanagari, Thai, Laotian and
many other scripts -- support for {elvish} is planned for a future
release).
