The Xfce4 Dictionary does not properly handle a Format Code \ .......... \. This code is placed around the text and Xfce4 Dictionary highlight this text with a italics and green colour. But at the time when this Formatting code no places on the first line then Formatting Text displayed not properly. As a demonstration of this error can be a dictionary under the title "The Collaborative International Dictionary of English v.0.48", which is on the server dict://dict.org, (or package called dict-gcide). Enter the phrase: "Aaronic".
