I prefer to post this thing here because it could that I'm doing
something wrong.
I'm using std.stdio -> readln() to read whatever I'm typing in
the console.
BUT, if the line contains some UTF-8 characters, the data
obtained is EMPTY and
<code>
module runnable;
import std.stdio;
import std.string : chomp;
import std.experimental.logger;
void doSomethingElse(wchar[] data)
{
writeln("hello!");
}
int main(string[] args)
{
/* Some fix I found to fix UTF-8 related problems, I'm using
Windows 10 */
version(Windows)
{
import core.sys.windows.windows;
if (SetConsoleCP(65001) == 0)
throw new Exception("failure");
if (SetConsoleOutputCP(65001) == 0)
throw new Exception("failure");
}
FileLogger fl = new FileLogger("log.log");
wchar[] readerBuffer;
readln(readerBuffer);
readerBuffer = chomp(readerBuffer);
fl.info(readerBuffer.length); /* <- if the readed string
contains at least one UTF-8
char this prints 0, else
it prints its length
*/
if (readerBuffer != "exit"w)
doSomethingElse(readerBuffer);
/* Also, all the following code doesn't run as expected, the
program doesn't wait for
you, it executes readln() even without pressing/sending a
key */
readln(readerBuffer);
fl.info(readerBuffer.length);
readln(readerBuffer);
fl.info(readerBuffer.length);
readln(readerBuffer);
fl.info(readerBuffer.length);
readln(readerBuffer);
fl.info(readerBuffer.length);
readln(readerBuffer);
fl.info(readerBuffer.length);
return 0;
}
</code>
The real code is bigger but this describes the bug. Also, if it
needs to print UTF-8 there's no problem.
My main problem is that the line is gonna be sended through a TCP
socket and I wanna make it work with UTF-8. I'm using WCHAR
instead of CHAR with the hope to get less problems in the future.
I you comment the fixed Windows code, the program crashes
http://prntscr.com/ajmy14
Also I tried stdin.flush() right after the first readln() but
nothing seems to fix it.
I'm doing something wrong?
many thanks.
