The brackets will display if the word processor is accepting the clipboard text as unformatted text. At one time you could specify which format to use. That option has now been combined into one so the OLB program now sends text out in both RTF and plain text to the clipboard. The text format that is used totally depends on the Word processor.
OpenOffice (which we use) will let us select the formatted (RTF) or unformatted text under “Edit – Paste Special…” You did not say which word processor you are using so you will have to check it out yourself. See the attached screen shot using OpenOffice.
Another thing, the formatted (RTF) font style and size can be changed by going to “Customize settings – fonts – printer font”.
