ASCII /as'kee/ n.
[originally an acronym (American
Standard Code for Information Interchange) but now merely
conventional] The predominant character set encoding of present-day
computers. The standard version uses 7 bits for each character,
whereas most earlier codes (including early drafts of ASCII
prior to June 1961) used fewer. This change allowed the inclusion
of lowercase letters -- a major win -- but it did not
provide for accented letters or any other letterforms not used in
English (such as the German sharp-S
or the ae-ligature
which is a letter in, for example, Norwegian). It could be worse,
though. It could be much worse. See EBCDIC to understand
how. A history of ASCII and its ancestors is at
http://www.wps.com/texts/codes/index.html.
Computers are much pickier and less flexible about spelling than
humans; thus, hackers need to be very precise when talking about
characters, and have developed a considerable amount of verbal
shorthand for them. Every character has one or more names -- some
formal, some concise, some silly. Common jargon names for ASCII
characters are collected here. See also individual entries for
bang, excl, open, ques, semi, shriek,
splat, twiddle, and Yu-Shiang Whole Fish.
This list derives from revision 2.3 of the Usenet ASCII
pronunciation guide. Single characters are listed in ASCII order;
character pairs are sorted in by first member. For each character,
common names are given in rough order of popularity, followed by
names that are reported but rarely seen; official ANSI/CCITT names
are surrounded by brokets: <>. Square brackets mark the
particularly silly names introduced by INTERCAL. The
abbreviations "l/r" and "o/c" stand for left/right and
"open/close" respectively. Ordinary parentheticals provide some
usage information.

The pronunciation of # as `pound' is common in the U.S.
but a bad idea; Commonwealth Hackish has its own, rather more
apposite use of `pound sign' (confusingly, on British keyboards
the pound graphic
happens to replace #; thus Britishers sometimes call
# on a U.S.-ASCII keyboard `pound', compounding the
American error). The U.S. usage derives from an old-fashioned
commercial practice of using a # suffix to tag pound weights
on bills of lading. The character is usually pronounced `hash'
outside the U.S. There are more culture wars over the correct
pronunciation of this character than any other, which has led to
the ha ha only serious suggestion that it be pronounced
`shibboleth' (see Judges 12:6 in an Old Testament or
Tanakh).
The `uparrow' name for circumflex and `leftarrow' name for
underline are historical relics from archaic ASCII (the 1963
version), which had these graphics in those character positions
rather than the modern punctuation characters.
The `swung dash' or `approximation' sign is not quite the same
as tilde in typeset material
but the ASCII tilde serves for both (compare angle brackets).
Some other common usages cause odd overlaps. The #,
$, >, and & characters, for example, are all
pronounced "hex" in different communities because various
assemblers use them as a prefix tag for hexadecimal constants (in
particular, # in many assembler-programming cultures,
$ in the 6502 world, > at Texas Instruments, and
& on the BBC Micro, Sinclair, and some Z80 machines). See
also splat.
The inability of ASCII text to correctly represent any of the
world's other major languages makes the designers' choice of 7 bits
look more and more like a serious misfeature as the use of
international networks continues to increase (see software rot). Hardware and software from the U.S. still tends to embody
the assumption that ASCII is the universal character set and that
characters have 7 bits; this is a major irritant to people who
want to use a character set suited to their own languages.
Perversely, though, efforts to solve this problem by proliferating
`national' character sets produce an evolutionary pressure to use
a smaller subset common to all those in use.
