Cygwin 2.6.0: unreadable UTF-8 in Windows console

[Ivan Vanyushkin <vanav@vanav.org>]

Something has changed in version 2.6.0, and now UTF-8 text can't be displayed in Windows console (cmd).

1. Create a file "test.txt" with non-ASCII text in UTF-8 encoding.
2. Run "cmd".
3. Run:

C:\Cygwin\bin\cat test.txt
â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’ â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’ â–’â–’â–’â–’ â–’â–’â–’â–’â–’â–’ 8000 â–’â–’. â–’â–’â–’â–’ â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’ â–’â–’â–’â–’â–’â–’â–’â–’â–’â–’.

Non-ASCII text is not readable. Older Cygwin 2.5.2 has no such issue.

C:\Cygwin\bin\uname -a
CYGWIN_NT-10.0 PCName 2.6.0(0.304/5/3) 2016-08-31 14:32 x86_64 Cygwin

C:\Cygwin\bin\locale
LANG=
LC_CTYPE="C.UTF-8"
LC_NUMERIC="C.UTF-8"
LC_TIME="C.UTF-8"
LC_COLLATE="C.UTF-8"
LC_MONETARY="C.UTF-8"
LC_MESSAGES="C.UTF-8"
LC_ALL=

Same issue with any other commands like "grep", or with utilities built and run under Cygwin 2.6.0.
Same issue in other Windows consoles, like ConEmu or FAR Manager.
If I change Windows console encoding to UTF-8 (run: "chcp 65001"), file can be correctly displayed natively
(run: "type test.txt"), but Cygwin "cat" still has the same issue.

How should I display UTF-8 now?

Thank you.
