I have tried to create the RTF text from html when try this my html content have the text(★). In my RTF text has mentioned below,

```
string rtf = @"{\rtf1{\fonttbl{\f0\froman Times New Roman;}{\f1\fnil Arial;}}{\colortbl;\red238\green122\blue3;}{{\pard {\f1 \sl240\slmult1 {\b\fs24\par \qc \cf1 {XhtmlCells}\par}{\b\fs20\par \qc \cf1 {★★★✩✩}\par}{{XhtmlCells use the }{\b { RichTextBoxSupportsXHTML}}{ control from GotDotNet user samples to display XHTML formatted text inside a cell.}\par}}}}}";

```

I have tried to load this text in RichTextBox1.Rtf which will be shown the "?" instead of "★".

Can you please suggest me how to display this star symbol in RichTextBox.
Thanks in advance
