Hmm. It is not likely that Roots/UFT used the MS Linedraw Font for any of its report writing efforts, or else it would have been discussed before on this forum.
It is also not likely (for copyright reasons) that the MS Linedraw font is functionally identical, character location for character location, to the Wordperfect box drawing font (character)set.
But for any one caring to experiment, it may be that the only way to do so is to export in the "automatic Launch to Wordperfect 7 mode". Then it will probably be necessary to go to Win.ini and do a global substitution of the the MS Linedraw font for the Wordperfect Boxdraw font.
Not recommended, imho. Been there, done that while trying to get UFT to print in Russian Cyrilic characters.:) John
