problems with encoding for different locales

[Joshua Stewart]

Hi,
I am trying to characterise a problem I am seeing on our C#/C++ xml
driven application. We have recently added some basic Spanish language
support to our application, but it seems that there is an issue with
certain locale settings.

Under Regional and Language Options -Standards and Formats I would
normally change the applications language by selecting Spanish (Mexico).
It looks like the application ignores the Location field.

However if I set the Standards and Formats drop-down to Spanish (Chile),
the application raises an exception when processing the XML data, as
it is suddenly getting out of range values.

What is the difference between these two locales?
After some further testing I noticed that about half the Spanish
language locales will work fine and the other half will give the exception.

All the xml is encoded UTF-8.
I suspect that some Spanish locales require greater than UTF-8 support.

Would encoding to Windows-1252 help possibly?

Any help, info, or pointers are appreciated :)
Thanks

Josh

What kind of XML API do you use exactly? Which error do you get exactly?

We are using C# reflection to create objects from the XML. We are using
C# XML features.
Here is the exception being raised .
I am keen to understand what the differences are between these two
locales (and other Spanish locales).
I only get the exception below on certain Spanish locales.. some work,
some dont.

The problem ended up being calls to Convert intead of XmlConvert (as
well as some tricky directx problems)
here is some further dicussion on it
