Re: innerHTML = responseText generates invalid chars

Actually the single quote is some sort of backward single quote.
There are also other characters not displaying correctly after
innerHTML = responseText.

I'll try to cover all the steps you noted above.

When I assign responseText to innerHTML, sometimes because of the

Does anyone comes across this frequently? What can I can do to make
the characters display properly?

Make sure the server sends a HTTP Content-Type response header with a
charset parameter e.g.
Content-Type: text/plain; charset=Windows-1252

Windows-1252 is only an example, obviously you need to set the encoding
there that your text is encoded with.

Adding 'charset=' is always a good idea, but I would avoid the
proprietary Windows-1252, especially because the original poster
surmises it is a Windows/UNIX issue.

I suggest to add a character set at the following places:
1. HTTP header of the program that outputs the data:
Content-Type: text/html; charset=ISO-8859-1
2. Inside the output file itself:
<?xml version="1.0" encoding="ISO-8859-1"?>
3. HTTP header of the receiving HTML-file:
Content-Type: text/html; charset=ISO-8859-1
4. As <meta> in the header of the receiving HTML-file:
<meta http-equiv="Content-Type"
content="text/html; charset=ISO-8859-1">

The original poster mentions that it [quote] "is especially true for
single quotes from text content". Since single quote is an ASCII-safe
character, it makes me think that it has something to do with the DTD
of the XML. '&apos;' is one of the five default character entities in
XML besides '&quot;', '&amp;', '&lt;' and '&gt;'.
