Character Set Confusion
Because these ASCII extensions have so many variants, it is necessary to identify which set is being used for a particular text for it to be interpreted correctly. However, because the most-used characters (those in ASCII, the seven-bit code points) are common to all sets—even most proprietary ones—failure to correctly identify a character set often suffers no adverse consequences if the user is typing in English. Further, because many Internet standards use ISO 8859-1, and because Microsoft Windows (using the code page 1252 superset of ISO 8859-1) is the dominant operating system for personal computers today, unannounced use of ISO 8859-1 is quite commonplace, and may generally be assumed without evidence to the contrary.
In many protocols, most importantly e-mail and HTTP, the character encoding of content has to be tagged with IANA-assigned character set identifiers.

Famous quotes containing the words character, set and/or confusion:
“For character too is a process and an unfolding ... among our valued friends is there not someone or other who is a little too self confident and disdainful; whose distinguished mind is a little spotted with commonness; who is a little pinched here and protruberent there with native prejudices; or whose better energies are liable to lapse down the wrong channel under the influence of transient solicitations?”
—George Eliot [Mary Ann (or Marian)
“Nothing in medieval dress distinguished the child from the adult. In the seventeenth century, however, the child, or at least the child of quality, whether noble or middle-class, ceased to be dressed like the grown-up. This is the essential point: henceforth he had an outfit reserved for his age group, which set him apart from the adults. These can be seen from the first glance at any of the numerous child portraits painted at the beginning of the seventeenth century.”
—Philippe Ariés (20th century)
“When heaven and earth were in confusion hurl’d
For the debated empire of the world,
Which awed with dreadful expectation lay,
Soon to be slaves, uncertain who should sway:”
—Lucretius (Titus Lucretius Carus)
