I'd just like to start this thread by saying that I have absolutely NO knowledge of PHP what so ever. I do mostly C++, C#, and Java. But my dad is having a problem so I am posting this as a favor.
My dad has his business run pretty much by PHP scripts on his server. People buy the software and they payment info is sent to his server, where everything is processed and a serial number is sent out.
He's not really sure what happened but now there is an error is one of the scripts. It says something about UniCode Normalization unsuccessful on an ASCII file(or input, not sure).
Any ideas why?
