+\subsubsection{The \texttt{keep-semicolon} attribute}

+The LGR font encoding uses the Latin question mark as input for the
+\emph{erotimatiko} and maps the semicolon to a middle dot (\emph{ano

+\emph{erotimatiko} end up with an \emph{ano teleia} in its place:

+SEMICOLON after drag-and-drop or other processing and with a middle dot in
+the final output.

+With the \texttt{keep-semicolon} language attribute, 003B SEMICOLON is made
