I want to share binary built under Cygwin 2.6.0 with other user, that has no LANG set.
In previous version all binaries worked correctly with UTF-8 input text.
But now this doesn't work as expected.

Some more simple tests.

// Run Windows console.
cmd

C:\Cygwin_2.6.0\bin\echo ±5°
▒▒5▒▒

C:\Cygwin_2.6.0\bin\echo ±5°|C:\Cygwin_2.6.0\bin\grep .
▒▒5▒▒
// Bad in Cywgin 2.6.0. Maybe this is UTF-8? See below.

// Now try in previous version.
C:\Cygwin_2.5.2\bin\echo ±5°
±5°

C:\Cygwin_2.5.2\bin\echo ±5°|C:\Cygwin_2.5.2\bin\grep .
±5°
// Good in Cygwin 2.5.2.


// Looks like changing console to UTF-8 codepage may fix the issue?
chcp 65001
Active code page: 65001

C:\Cygwin_2.6.0\bin\echo ±5°
▒▒5▒▒

C:\Cygwin_2.6.0\bin\echo ±5°|C:\Cygwin_2.6.0\bin\grep .
▒▒5▒▒

echo ±5°
±5°

echo ±5°|C:\Cygwin_2.6.0\bin\grep .
▒▒5▒▒
// Bad in Cygwin 2.6.0. Seems this is not UTF-8, just broken text.

// Now try in previous version.
C:\Cygwin_2.5.2\bin\echo ±5°
±5°

C:\Cygwin_2.5.2\bin\echo ±5°|C:\Cygwin_2.5.2\bin\grep .
±5°

echo ±5°
±5°

echo ±5°|C:\Cygwin_2.5.2\bin\grep .
±5°
// Works good in Cygwin 2.5.2 even with native "echo", because it produces UTF-8 now.
