Unicode characters while copying text from Word in RadEditor while exporting to RTF

[Sushma]

Hi Team,

We are using RadEditor in our MVC application. Content entered or copied is converted to RTF format and then saved to database.

But when we copy text like following from Microsoft word:- Text  for “Unicode ‘Testing’ Test” (text containing quotes entered in MS word) ,       after exporting to RTF, it is converting to Unicode characters as following :-    \u8220?UniCode \u8216?Testing\u8217? Test\u8221.

 

Even when we disable the filter of ConvertCharactersToEntitiesas shown below, still it is not working.

RadEditor1.DisableFilter(Telerik.Web.UI.EditorFilters.ConvertCharactersToEntities));

Instead of replacing the above characters by hardcoding them, is there any possible way to avoid this Unicode conversion. Please let us know if it is possible.

Thanks in Advance,

Sushma Katneni

Hi Sushma,

The pasting is not controlled by RadEditor as explained in https://docs.telerik.com/devtools/aspnet-ajax/controls/editor/managing-content/pasting-content/overview#radeditor-and-the-browser-clipboard and these character come from the clipboard.

Here is the list of the characters which are converted by RadEditor and as you can see the ones you provided are not in the list:

You can test with an editable iframe/div by pasting the original word content into it and inspecting what is pasted using the browser HTML inspector. You can use this demo which will render editable div and iframe in the browser after hitting the Run button - http://dojo.telerik.com/@nlazarov/IFIPAR.

As to RadEditor - you have two options to control the content and modify it as per your requirements:

• handle the pasted content in the OnClientPasteHtml event
• handle the produced content via a custom content filter or by replacing the HTML entities using String.Replace -> RadEditor1.Content = RadEditor1.Content.Replace("\u8217", "”");
