Numeric Character reference when saving to HTML format
in C# and VB.NET


    A numeric character reference (NCR) is a common markup construct used in SGML and other SGML-related markup languages such as HTML and XML. It consists of a short sequence of characters that, in turn, represent a single character from the Universal Character Set (UCS) of Unicode.

In case of 'true': Write the all characters in "NCR" notation: &#xxx;. In case of 'false': Write the all characters as Unicode (recommended). Default value: false.
