That sounds very strange to me, becaus I use utf8 for everything I write and I have never had any problems with it.
You may think it's encoded in utf8 but then it may not be. It could be your edit not using utf8 etc.
Like I said above, I use utf8 for all of config files with no problems I also use utf8_unicode_ci for all my databases with no problems.
Also your file is wrong in the autoload.php it should be all lowercase!
