The boost signal was sent synchronously, and so made the Qt signal to be posted
in FileMonitor::changed after the boost signal returned, so after the sender was
possibly destroyed.
The solution is to make the boost signal asynchronous using the Qt event loop.
Thanks to Scott Kostyshak for the report and MWE.

With Qt 5.11 at least, RtL text will be drawn RtL even when the
(undocumented) flag Qt::TextForceLeftToRight is applied to the
QTextLayout object. This creates selection issues for Hebrew text
marked as English.
The solution is to do the same as in breakAt_helper, that is prepend
the string with a direction override unicode character.
Doing this requires to introduce a TEXTLAYOUT_OFFSET constant that has
to be used wisely to account for this extra character.
Fixes bug #11284.

As of LaTeX2e 2018, characters are made active earlier, which results
in new expansion problems.
Following a suggestion of Markus Kohm (pc) and the TL mailing list [1],
we embrace non-ASCII input paths in \detokenize. This relies on e-tex,
but I think we can assume this is nowadays available everywhere.

When deciding how to strike out deleted math in change-tracking
mode, differentiate only on begin-of-line or not, and not on
after-paragraph-break or not.
The assumption that a new paragraph is always started after a
float seems to be not true and was causing this bug.

This is a fixup to 4ecbff00. When a file is loaded and the cursor is
set, it is required to first compute metrics to be able to scroll the
