About posts created on Facebook wall

Well i use new Unity 3D Facebook sdk, it works very well for me, i have not any difficult to use it for my needs, but some result needs to be correct. i installed a webplayer app inside facebook and it works well, but when i click share button it shows a windows with my exact content, so user can click "condivide", when he meade this i repeat it works well and post the content on facebook wall. When i seek the content in wall i find it soon, but the post don't show all my text!! When inside code i have added newline in app windows it show correct line but in facebook wall it show my message truncated with ..... So i ask why in app is showed correct (i can say correct at 80% because there are some issues with window size..), but on fb there this .....??? If it is necessary i can post address of my app on request. thanks.
