|
||
|
|
<div><p>The Character Data Representation Architecture (CDRA) system of
|
||
|
|
tags uses an encoding scheme to specify many rules.</p>
|
||
|
|
<p>The rules include:</p>
|
||
|
|
<ul><li>The coding space (number and allowable value of code points in a code
|
||
|
|
page)</li>
|
||
|
|
<li>Rules for sharing the coding space between control and graphic characters</li>
|
||
|
|
<li>Rules related to specific options, such as the number bytes required for
|
||
|
|
each character (single-byte, double-byte, or mixed-byte) permitted in that
|
||
|
|
scheme</li>
|
||
|
|
<li>Rules related to code extension techniques (if used)</li>
|
||
|
|
</ul>
|
||
|
|
<p>The rules for encoding schemes are followed when code points are assigned
|
||
|
|
to graphic characters in a particular code page. Some common encoding schemes
|
||
|
|
are Extended Binary Coded Decimal Interchange Code (EBCDIC) and American Standard
|
||
|
|
Code for Information Interchange (ASCII).</p>
