Re: [docbook-apps] Docbook xml title containing double quotation marks causes CHM TOC issue

Hi Chris,

Thank you for sharing your ideas. I have very limited knowledge to entities 
and encoding, so I did some researches and tried to understand what you 
said, please correct me if my understanding is incorrect.

I tested and found that all the following writing styles produce the same 
result in the hhc file and the html file.
I may assume that they are replacements for one another and all working in a 
portable and standard manner. Difference is “ pair is decimal numeric 
character references, and “ pair is hexadecimal. And since XML allows 
both decimal and hexadecimal numeric character references, so I would assume 
there is no difference between them that I need to pay special attention to. 
Or is there one preferable over the other?

And “ and ” are HTML character entity references, as I copied them 
from a list named THML escape chracters. At first, I just wanted to give it 
a try, but it turned out to work. However, I still don't understand why they 
happened to work in an xml file, what their actual meanings are in the xml 
numeric reference, and how Windows CP-1252 encoding interferes with the 
result. I will do more reseraches later. But if anybody could shed me some 
lights on this, I will certainly appreciate it.

XML file:
  <sect1>
    <title>Loading <quote>heavy</quote> window1</title>
  </sect1>

  <sect1>
    <title>Loading &#8220;heavy&#8221; window2</title>
  </sect1>

  <sect1>
    <title>Loading &#x201c;heavy&#x201d; window3</title>
  </sect1>


HHC file:
<param name="Name" value="Loading &#8220;heavy&#8221; window1">

<param name="Name" value="Loading &#8220;heavy&#8221; window2">

<param name="Name" value="Loading &#8220;heavy&#8221; window3">

Regards
Tracy
