\item wxRICHTEXT\_SETSTYLE\_CHARACTERS\_ONLY: specifies that the style should only be applied to characters,
and not the paragraph. This allows content styling to be preserved independently from that of e.g. a named paragraph style.
\item wxRICHTEXT\_SETSTYLE\_RESET: resets (clears) the existing style before applying the new style.
+\item wxRICHTEXT\_SETSTYLE\_REMOVE: removes the specified style. Only the style flags are used in this operation.
