HelpFindWindow?

Hey! First of all, sorry for my english. So. My question is what is the diffetence between FindWindowA and W? i used A all my life... but now i found a guy who is useing W. And how can i use FindWindowW? many thanks Same way as A? you know (NULL, "windowname")? Thanks

"The documentation gives the basic name of the function (FindWindow) but
since it takes strings there are two versions, a Unicode one (FindWindowW)
and Ansi (FindWindowA)"
