How to inserts question marks when using formatting of text in Rich Text Editor

[Syncfusion Support]

Answer:

We can achieve this by replacing the non-zero width space with the empty value in the Rich Text Editor content before using or saving the value.

<SfRichTextEditor @bind-Value="@rteValue">  

</SfRichTextEditor>  

  

<SfButton Type="submit" CssClass="e-primary" @onclick="@SaveText">Save</SfButton>  

  

@code {  

    public string rteValue { get; set; }  

    public void SaveText()  

    {  

        // Before using the value of the Rich Text Editor perform the below actions to remove the question mark.  

        Regex rgx = new Regex(@"[\uFEFF\u200B]");  

        this.rteValue = rgx.Replace(this.rteValue, "");  

    }  

}
