Docx format can encode symbol characters using the <sym> element. Currently this concept is not supported in the document model, and the element is converted to normal character on import. Add support for similar element in the document model, and for its export to Docx.
The item was logged improperly. We've fixed it and some of your votes have been migrated to the proper item - RichTextBox: Add support for SYMBOL field (http://feedback.telerik.com/Project/143/Feedback/Details/204071 ).
Really a required feature! Very frequently it happens when we copy data from some word file, it removes some important special character! Good initiative :D
