Discrepancy between size of DESTPAGETITLE generated at word import and database contraints

On attempted import of a word document with some very long section headings the following error appears in the log:

This looks to me like the import function allows one character more than the length the database field was configured for. Perhaps this is an unaccounted-for terminator such as a linefeed.
