yeah,we explored itext and found that there aren't any classes to handle such char's.the user can input his research paper in two ways.one is the way that i told to you earlier ie uploading a doc file.other way is to copy and paste every paragraph in the paper in the text boxes provided by us.if there are any equations then we ask the user to extract the entire equation from the paper as an image and upload it in the same way he does with any image.so,if at all i want to write equations onto a pdf file using itext,i have to upload it as an image.thanks for all the information provided to me.
