Delphi XE - should I use String or AnsiString?

Question

I finally upgraded to Delphi XE. I have a library of units where I use strings to store plain ANSI characters (chars between A and U). I am 101% sure that I will never ever use

Answer 1

In general only use AnsiString if it is important that the Chars are single bytes, Otherwise the use of string ensures future compatibility with Unicode.
