Titles editing problems

Using v2 (1efc609) and making some copy/paste in titles/subtitles/etc. I noticed some strange behaviours :

1/ It is not possible to cut and paste juste to copy and paste.
2/ When I select some text and copy it, it take in the clipboard one character before my selection plus everything until the end of line.
For exemple, if I select "em" in a the title "My exemple" and paste it in subtitle, I paste "xemple".
