XML Encoding

[viepia]

Hi,

In program 1 XmlWriter.Create(string pathname, XmlWriterSettings
settings), its encoding is UTF-8 <?xml version="1.0"
encoding="utf-8"?>, in program 2 XmlWriter.Create(StringWriter stw,
XmlWriterSettings settings), it encoding is UTF-16 <?xml version="1.0"
encoding="utf-16"?>
. The settings are identical in each program. The XML text is
saved as 8 bit ASCII in each program, so "utf-16" is wrong in Program
2. What can I do to get Program 2 to make the correct "utf-8"
header?

Thanks,
Viepia

In program 1 XmlWriter.Create(string pathname, XmlWriterSettings
settings), its encoding is UTF-8 <?xml version="1.0"
encoding="utf-8"?>, in program 2 XmlWriter.Create(StringWriter stw,
XmlWriterSettings settings), it encoding is UTF-16 <?xml version="1.0"
encoding="utf-16"?>
. The settings are identical in each program. The XML text is
saved as 8 bit ASCII in each program, so "utf-16" is wrong in Program
2.

Well, firstly there's no such thing as 8 bit ASCII. The first version
is saving it as UTF-8.

Secondly, the second version is only saving it to a StringWriter. If
you choose to then save that string to disk as UTF-8 instead of UTF-16,
that's your choice rather than .NET getting it wrong on your behalf.
However...

What can I do to get Program 2 to make the correct "utf-8"
header?

You want a StringWriter which returns UTF-8 as the encoding. I have a
StringWriterWithEncoding class in my MiscUtil library:

The StringWriterWithEncoding class worked great. Thanks!
