Ogre model error

Hello

I exported my blender model via Ogre2Mesh. It work in sceneComposer with animations etc. When i load it into the game as a static model at x,y,z it work. But when I want to use that model as my player model i get error:
[java]
WARNING: Your export has been saved with an incorrect encoding for it’s String fields which means it might not load correctly due to encoding issues. You should probably re-export your work. See ISSUE 276 in the jME issue tracker.[/java]

I use 3rd person camera code from: https://wiki.jmonkeyengine.org/legacy/doku.php/jme3:user_examples:ThirdPersonCamera

Can you post the entire exception?
