Summary0006785: crt garbles writeln() output
DescriptionSimply include "uses crt;" and your write() output is garbled.
I use russian language, win32, codepage 1251. Some symbols are substituted by question marks, some --- by other symbols.
CRT docs don't mention it openly, some other unfixed bugs don't seem to state this exact problem.

I applied a patch from Maxim Ganetsky to fix this issue in 2.1.1. Can you please test and tell me if it works for you?

I want to add that this patch won't work in all cases. It makes console output work on default configuration (with Terminal font), but garbles output with Lucida console font. Without this patch it is the other way round. Without Crt it will work in either case. Microsoft console is a mess ;)

But IMO it is still better than previous situation.

I mark it as resolved for now, let's see if people still complain.

I believe that the patch was in fact wrong and that the supplied code fragment should be rejected as not relevant for a bug report. The problem is that the provided code uses Unicode characters whereas unit Crt assumes working with traditional code pages (we may be able to change that with the Unicode string support being added recently, but that is another story). The applied patch forces all output with unit Crt to use the so called ANSI code page regardless of the code page selection performed by the user (e.g. using chcp in the particular console window before running the program or programmatically using SetConsoleCP). This is IMHO wrong. Rather than trying to reopen this bug, I'll file a new one (and link it to this one).
