Code Page - Criticism

Criticism

Many older character encodings, except Unicode, suffer from several problems.

  1. Some code page vendors insufficiently document the meaning of all code point values. This decreases the reliability of handling textual data through various computer systems consistently.
  2. Some vendors add proprietary extensions to some code pages to add or change certain code point values. For example, byte \x5C in Shift JIS can represent either a back slash or a yen currency symbol depending on the platform.
  3. In order to support several languages in a program that does not use Unicode, the code page used for each string/document needs to be stored.

Due to Unicode's extensive documentation, vast repertoire of characters and stability policy of characters, these problems are rarely a concern for Unicode.

Applications may also mislabel text in Windows-1252 as ISO-8859-1. Fortunately, the only difference between these code pages is that the code point values used by ISO-8859-1 for control characters are instead used as additional printable characters in Windows-1252. Since control characters have no function in HTML, web browsers tend to use Windows-1252 rather than ISO-8859-1.

Famous quotes containing the word criticism:

    I hold with the old-fashioned criticism that Browning is not really a poet, that he has all the gifts but the one needful and the pearls without the string; rather one should say raw nuggets and rough diamonds.
    Gerard Manley Hopkins (1844–1889)

    The critic lives at second hand. He writes about. The poem, the novel, or the play must be given to him; criticism exists by the grace of other men’s genius. By virtue of style, criticism can itself become literature. But usually this occurs only when the writer is acting as critic of his own work or as outrider to his own poetics, when the criticism of Coleridge is work in progress or that of T.S. Eliot propaganda.
    George Steiner (b. 1929)

    A tailor can adapt to any medium, be it poetry, be it criticism. As a poet, he can mend, and with the scissors of criticism he can divide.
    Franz Grillparzer (1791–1872)
