Crystal Reports 10 - Displaying superscript & subscript characters from db

Hi,

We are working on a application that uses asp.net and crystal reports. The issue is that certain information has to be shown as a superscript or subscript characters. Example is shown below:

<superscript>99m<superscriptTc

<superscript>13<superscript>NH<subscript>3<subscript>

The content is typed in a RTF based editor and the RTF text is stored in the DB. When the report is pulled out the report is supposed to be displayed with the superscript and subscript characters.

Could anyone let me know how this can be achieved as I understand that crystal report does not support superscript and subscript characters.
