This is a common issue.
one of the easiest way to solve is to check if the special character is reaching inside the action layer and then modifying the special character in the java code.
If you are able to view this character in Action or any other java layer of your choice (Like business layer), just replace the character with corresponding HTML character using the StringEscapeUtils.html#escapeHtml
After doing the escape. use the new string to save to the DB.
