OK, so here are finally my updated test results:


resize terminal while running Windows cmd
run cmd, resize, run dir/P:
✓works


terminal reports in response to request escape sequences
("\033[6n", "\033[0c", "\033[>c", '\033[18t', '\033]10;?\033\')
✓works


output to alternate screen
echo -e "\e[?1047h"; cmd
✓works
cmd
from other terminal: echo -e "\e[?1047h" > /dev/pty...
↯no output; weird behaviour on ^C, mintty terminating (also in 3.1.6)


signal handling/mediation; catch SIGTSTP
run notepad, click back into terminal, enter ^Z
↯fails, notepad is terminated
-> this is a regression, ^Z,^C,^\ used to be ignored


character set conversion from Windows cmd line program
run xcopy (Windows system language e.g. German), watch error message
✓works in Unicode terminal
✓works in non-Unicode terminal (e.g. LC_ALL=C.CP850 mintty)


handling non-ASCII characters in non-Unicode terminal + native interworking
LC_ALL=en_US mintty, check locale charmap -> ISO-8859-1
echo ö | od -t x1 -> 0xF6
✓works
cmd /c echo ö | od -t x1 -> 0x94
↯fails (also in cygwin 3.1.6)


using wincon.c, compiled with x86_64-w64-mingw32-gcc
run program, check colour of second output, give non-ASCII input, check echo
✓works in Unicode mintty
✓works in non-Unicode mintty


using attached wincon.c, compiled with gcc
run program, check colour of second output, give non-ASCII input, check echo
↯no output (regression, works in 3.1.6)


using attached program sgr.java
run program, check coloured output of middle characters
✓works (did not in 3.1.6)
