In the table above, the cells with non-white background emphasize the differences from the US variant used in the Basic Latin subset of ISO/IEC 10646 and Unicode.

The characters displayed in cells with red background could be used as combining characters, when preceded or followed with a backspace C0 control. This encoding method may be considered deprecated.

Later, when wider character sets gained more acceptance, ISO 8859, vendor-specific character sets and eventually Unicode became the preferred methods of coding most of these variants.

Famous quotes containing the words national and/or variants:

“Public speaking is done in the public tongue, the national or tribal language; and the language of our tribe is the men’s language. Of course women learn it. We’re not dumb. If you can tell Margaret Thatcher from Ronald Reagan, or Indira Gandhi from General Somoza, by anything they say, tell me how. This is a man’s world, so it talks a man’s language.”
—Ursula K. Le Guin (b. 1929)

“Nationalist pride, like other variants of pride, can be a substitute for self-respect.”
—Eric Hoffer (1902–1983)
