Fix for .NET websites

• In the publishing package, check if UTF-8 is enabled.  If UTF-8 is not enabled, try republishing.  When UTF-8 encoding is not enabled, the output is HTML entities and would not cause UTF-8 encoding errors.

<system.web>
<globalization fileEncoding="utf-8" requestEncoding="utf-8" responseEncoding="utf-8" />
</system.web>
