commit f5ac0580ff8f4f1fd34d792f7952fb05d182e162
Author: Günter Milde <[email protected]>
Date: Mon Mar 6 14:49:30 2017 +0100
special character "allowbreak" (ZWSP), fileformat change
New special character to mark an optional line break
without inserting a hyphen (ZWSP). See #10585.
Corresponds to the Unicode character U+200B ZERO WIDTH SPACE
This isn't a “space”. It is an invisible character that can be used
to provide line break opportunities.
http://unicode.org/notes/tn27/
While the literal Unicode character can be used in the LyX
file, it is invisible in the GUI.
For visible feedback, the patch adds a new special character "allowbreak".
The small mark is inspired by LibereOffice.
A tooltip is added.
