Usage in Computer Readable Languages
For programming languages and document languages such as C and HTML, the principle of Extended ASCII is important, since it enables many different encodings and therefore many human languages to be supported with little extra programming effort in the software that interprets the computer readable language files.
The principle of Extended ASCII means that:
- all ASCII bytes (0x00 to 0x7F) have the same meaning in all variants of extended ASCII,
- bytes that are not ASCII bytes are used only for free text, not for tags, keywords and other features having special meaning to the interpreting software.

Famous quotes containing the words usage, computer, readable and/or languages:
“Girls who put out are tramps. Girls who don’t are ladies. This is, however, a rather archaic usage of the word. Should one of you boys happen upon a girl who doesn’t put out, do not jump to the conclusion that you have found a lady. What you have probably found is a lesbian.”
—Fran Lebowitz (b. 1951)
“What, then, is the basic difference between today’s computer and an intelligent being? It is that the computer can be made to see but not to perceive. What matters here is not that the computer is without consciousness but that thus far it is incapable of the spontaneous grasp of pattern—a capacity essential to perception and intelligence.”
—Rudolf Arnheim (b. 1904)
“He has the earnestness of a prophet. In an age of pedantry and dilettantism, he has no grain of these in his composition. There is nowhere else, surely, in recent readable English, or other books, such direct and effectual teaching, reproving, encouraging, stimulating, earnestly, vehemently, almost like Mahomet, like Luther.... His writings are a gospel to the young of this generation; they will hear his manly, brotherly speech with responsive joy, and press forward to older or newer gospels.”
—Henry David Thoreau (1817–1862)
“Wealth is so much the greatest good that Fortune has to bestow that in the Latin and English languages it has usurped her name.”
—William Lamb Melbourne, 2nd Viscount (1779–1848)
