<TITLE>Test of invalid NCRs 128-159</TITLE>

<BODY><H2>Test of invalid NCRs 128-159</H2> 
<P> 
Authoring tools on MS Windows, in particular MS FrontPage ("WYSIWYG" HTML editor), 
generate invalid <DFN>Numerical Character References</DFN> for characters 
commonly found in positions 128...159 (0x80...0x9f) in Windows fonts.  Although 
these are valid codepoints for <em>windows-1252</em> (and other 
windows-xxxx) charsets, valid NCRs always refer to the document character set 
in the SGML sense, not to the character encoding scheme (or charset).  For HTML, 
the SGML document character set is fixed, it is always a subset of Unicode 
(or ISO 10646).  In Unicode and its iso-8859-1 subset, values 128...159 are 
C1 control characters, they must not appear in HTML.  Valid NCRs for the 
intended characters use Unicode values greater than 256. 
<p> 
Lynx tries to interpret some of the invalid codes, by assuming that they are 
windows-1252 codepoints.
