Compas Pascal

Compas Pascal
– One of the most frequent misunderstandings that I have seen about the Unicode migration of Delphi, is that many consider the Ansistring of Delphi 2007 and older, and all the Ansi functions in the APIs, to be about the ANSI character set. If you live in USA or any other country that uses ...
