+Learn how to address the issue where a special symbol (e.g. apostrophe character) is replaced by a copyright (or other) symbol in a filled PDF AcroForm using RadPdfProcessing. When the form is opened for editing in a viewer (like Adobe Acrobat), the character appears correctly as an apostrophe in the editor itself. 
+
+>note This might be reproduced with other symbols as well, not only with the apostrophe character.
 
 ## Solution
