Computer Basics
Character Codes
|
 |
ASCII codes are used in UNIX and DOS-based computers to represent plain
text. IBM System 390 computers use their own set of codes, called EBCDIC.
A new standard, called Unicode (Unicode
Worldwide Character Standard), is used on Windows NT computers. IE4+ and Netscape
4+ understand Unicode and its use is spreading. Unicode version 3.0 contains
49,194 characters from the scripts used to write
the major languages of the world. In addition to letters and numbers, Unicode
includes punctuation, mathematical and technical symbols, geometric shapes, dingbats, and
Braille patterns. Unicode contains the standard ASCII codes as a subset.
Tables below show the ASCII and EBCDIC code sets. The symbol
means that the current font does not contain the symbol. For example 0128 has recently been changed to
, the new Euro currency symbol, but older fonts will not have that symbol.
For images of the complete tables, see
www.asciitable.com
To see the glyphs for Unicode you need to go to the Unicode site:
Unicode 2.1 charts. There are some scripts here that are very different from what you see on this page!
Standard ASCII (just the alphanumeric characters)
