I'm having trouble with Unicode encoding in DOM. As a simple example,
I read in a UTF-8 encoded xml file such as:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<aText>letter 'a' with umlaut: ä</aText>
And when I serialize it, it comes out encoded as ISO-8895-1. But I
don't think the problem is with serialization. In processing my XML
files, I'm matching bits and pieces of text and attributes with some
Unicode/UTF-8 text read in from another souce. When the strings in my
XML file contain non-ASCII characters, then I have problems.
Hopefully, I've explained the problem enough so that someone can help.
In case it's necessary, I attach at the end, a bit of code for reading
in and serializing a DOM.
