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:

“...America has enjoyed the doubtful blessing of a single-track mind. We are able to accommodate, at a time, only one national hero; and we demand that that hero shall be uniform and invincible. As a literate people we are preoccupied, neither with the race nor the individual, but with the type. Yesterday, we romanticized the “tough guy;” today, we are romanticizing the underprivileged, tough or tender; tomorrow, we shall begin to romanticize the pure primitive.”
—Ellen Glasgow (1873–1945)

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