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:
“If there be no nobility of descent in a nation, all the more indispensable is it that there should be nobility of ascent—a character in them that bear rule, so fine and high and pure, that as men come within the circle of its influence, they involuntarily pay homage to that which is the one pre-eminent distinction, the Royalty of Virtue.”
—Henry Codman Potter (1835–1908)
“Scholarship cannot do without literature.... It needs literature to float it, to set it current, to authenticate it to all the race, to get it out of closets and into the brains of men who stir abroad.”
—Woodrow Wilson (1856–1924)
“[Allegory] should ... be very sparingly practised, lest, whilst the writer plays with his own fancies and diverts himself by cutting the air with his wide spread wings, he should soar out of view of his readers, leaving them in confusion and perplexity to explore his viewless track.”
—Sarah Fielding (1710–1768)
