You fixed my mistakes :)

Is that mean when i want to compile my project to UTF-8 (or Unicode),
that mean must change my variables to widestring, A:string to
A:widestring (i remember old discuss somewhere about this), is there a
string type switched between two types when i choose the unicode in
compile, or make "string" type be a widestring (that my mistake in
fact)?
