I have a server with Windows Server 2012 R2 and a PC with Windows 8.1, both are running the same configuration of PHP and Apache and I'm using TCPDF to make a pdf, but if I use characters like Ñ, Ü, É and the likes of those I get different results on my PC and in the server is there a way to change encoding in my pc to get the same result on both?
I use this to get the right result on the server:
mb_strtoupper($variable)
and this for the right result on my PC:
mb_strtoupper($variable, 'UTF-8')
