Hi -
I am using the Encoding class to encode unicode strings.
I am encoding into a variety of target encodings eg utf-8,
'iso-8859-1' or 'iso-8859-5' etc
like this:
encodedBytes = Encoding.GetEnc oding("iso-8859-1").GetBytes(Te xtBox1.Text);
anyone know a technique to cause exceptions to be thrown if there is
no corresponding mapping possible for any of the characters?
what is happening in practice is that they get converted into a '?'
symbol - but I'd rather an exception were thrown....
ta,

The usual way of doing that is by reversing the process, and seeing
whether or not you end up with the same string:
byte[] EncodeTextOrThr ow (Encoding encoding, string text)
{
byte[] ret = encoding.GetByt es(text);
string cycled = encoding.GetStr ing(ret);
if (cycled != text)
{
throw new ApplicationExce ption ("Could not encode text");
}
return ret;
}

Hi all,
I work on a translation module and I need to encode different
characters from different charset.
I've got an Access database that countains the different translations.
When I display the content of it, it works well (I set the page
charset to utf-8).
Now, I'd like to get each character code. For that, I use
Encoding.GetBytes function, as following:

Hi...
I've been doing a lot of work both creating and consuming web services, and
I notice there seems to be a discontinuity between a number of the different
cogs in the wheel centering around windows-1252 and that it is not equivalent
to iso-8859-1.
Looking in the registry under HKEY_CLASSES_ROOT\MIME\Database\Charset and
\Codepage, it seems that all variations on iso-8859-1 (latin1, etc) are
mapped to code page 1252, which I'm...

I have a software application I've written called PowerBlog (PowerBlog.net)
that takes the editing capability of the Internet Explorer WebBrowser
control (essentially a DHTMLTextBox), extracts the user-typed HTML, assigns
it as an XML node's InnerText property (using C#: System.Xml.XmlDocument
obj; obj.InnerText = myHTML). Then I later get the InnerText as a string and
write to disk.
When this text is displayed in a web browser, special...

Hi,
My native language is Icelandic and I´m making a web service that returns
results that contain many Icelandic characters. This works fine, however,
when I return a soap:Fault, the string in the faultstring element has the
Icelandic characters encoded like "réttindi", where "é" is an
Icelandic accented character.
Does anyone know why? If so, how do I deal with this?

When converting Unicode strings to legacy character encodings, it is
possible to register a custom error handler that will catch and process
all code points that do not have a direct equivalent in the target
encoding (as described in PEP 293).
The thing to note here is that the error handler itself is required to
return the substitutions as Unicode strings - not as the target encoding
bytestrings. Some lower-level gadgetry will silently...

XML gives an error when I have a £ sign (GBP) - £ - in a string.
I've fixed this by converting it to its HTML number.
In case other characters may cause the same error, I'm converting
characters to their HTML numbers that < 32 or 126 decimal.
Is this correct? What would you advise?
Thanking you in anticipation.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
