If you view the source code of the
pixelsocks interview you see that apostrophes are coded as "’" and that's what the SMF software is choking on. (Note: I added underscores ahead of the codes below so that you could see them)
"Unlike with 3D models, we can_’t modify the characters"
"We_’re not quite done with the game yet"
I haven't thoroughly sought out the other special character codes that cause the same text-drop yet but every little bit of light we can shine on this problem might help the forum programmer(s) reach a solution more quickly so keep sharing your discoveries, friends.
In the meantime be aware that just copying text from web sites and pasting it into your forum posts directly will probably result in some of the text being truncated. Your best solution is to either select the text you want to use from a "View Source" window and then manually removing special characters or just re-typing the text yourself.
