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.
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; this is a 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.
:ASCII art: n. The fine art of drawing diagrams using the ASCII
character set (mainly `|', `-', `/', `\', and
`+'). Also known as `character graphics' or `ASCII
graphics'; see also {boxology}. Here is a serious example:

There is an important subgenre of humorous ASCII art that takes advantage of the names of the various characters to tell a pun-based joke.

Within humorous ASCII art, there is for some reason an entire
flourishing subgenre of pictures of silly cows. Four of these are
reproduced in Figure 2; here are three more:
