Ok, I understand.
So readln is affected by the WideString Manager, and the WideString Manager
use operating system routines, (Windows). In linux I use cwstring. ok.
In this case, When I use readln. readln (cad);
The command interpreter uses 850 (cmd), but Windows uses 1252.
When I enter the symbol €, it converts it to ?. As I understand, because
this symbol does not exist in 850.
But when I use Writeln ('€'), no shows the question mark ?. As I
understand, it is because the symbol exists in 1252.
That is, When I use readln, then the Widestring manager use the charset of
the command interpreter (cmd 850), and when I use writeln, then the
Widestring manager, use the charset of the Operating System (ANSI-1252).
(only windows)
Am I right, or am I wrong?
thanks
