XtraRichEdit - Provide API to underline only words

The DevExpress.XtraRichEdit.API.Native.UnderlineType.UnderlineWordsOnly enumeration member specifies an underline that is a single line below all non-space characters. Other characters are not underlined.
The following code snippet underlines words in the first paragraph in red.

C#
DevExpress.XtraRichEdit.API.Native.DocumentRange range = richEditControl1.Document.Paragraphs[0].Range;  
DevExpress.XtraRichEdit.API.Native.CharacterProperties cp = richEditControl1.Document.BeginUpdateCharacters(range);  
cp.Underline = DevExpress.XtraRichEdit.API.Native.UnderlineType.UnderlineWordsOnly;  
cp.UnderlineColor = Color.Red;  
richEditControl1.Document.EndUpdateCharacters(cp);  

Visual Basic
Dim range As DevExpress.XtraRichEdit.API.Native.DocumentRange = richEditControl1.Document.Paragraphs(0).Range

cp.Underline = DevExpress.XtraRichEdit.API.Native.UnderlineType.UnderlineWordsOnly
