Thanks for the help @jmcilhinney and @Damith. I ended up cheating the system by doing a dirty. I saw that myRTB was replacing the form feed char with \page
in the RTF, but when I typed the form feed char myself it put \u9792
. Therefore I went with the hack:
myRTB.Rtf = myRTB.Rtf.Replace("\\page", "\\u9792");
If you have something less hackish that I can get working please let me know.
