This happens because you are trying to convert utf8 characters with htmlentites. Sadly the function does only work on ascii chars correctly. The easiest solution is to simple store your strings in your utf8 database table and output them with only htmlspecialchars instead of htmlentities.
Just be sure to set your page encoding to utf8.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
