I got it!
And you know what it was? As I said... I can read what I write in mIRC but I couldn't read the UTF8 Users.
DJ_Sol came up with $utfencode and explained everything well and it didn't work for me.
Got me thinking and then I thought utfencode... that is when I write something, but that was not my problem. The problem was with decoding. I changed it now to $utfdecode and guess what, it works!
Thanks anyway for leading me to the right thing and for your patience.
