Hello,

The following works fine

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i var 
 anarrowstring : pchar = 'this is a "narrow" string';...begin 
 writeln(anarrowstring);end. The compiler is, as expected, perfectly
happy with that.  On the other hand, if pchar is changed to pwidechar,
the compiler emits an error stating that variables of that type can
neither be read nor written.  e,g.  the following does not work :


Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i var 
 awidestring : pwidechar = 'this is a "wide" string';...begin 
 writeln(awidestring);end. 
Did I miss something or is it really the case that writeln cannot
write wide characters to the console ?   I can always import wprintf
from user32.dll but, I'd rather keep things "pascal" if possible.

Thank you for your help.

Cast to unicodestring?

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i program
untitled;var   awidestring : pwidechar = 'this is a "wide"
string'; begin   writeln(unicodestring(awidestring));end.
