Modified the generation of Unicode Strings in CS file

[artfuldev]

Unicode Strings of the format "&#x{1};" do not work from code behind. So instead used "\u{1}" format, and now it actually works from code behind. And generally tried to clean up some code and formatting.

Moved formats to the Create<<>>File() methods.
