When trying to run the hello world code on windows, it works if run from the native command prompt.

But when tried to run from cmder, it panics and says

panic: character set not supported

goroutine 1 [running]:
main.main()
        F:/go_dev/tview_hw.go:10 +0x167
exit status 2

If it helps, output of locale on cmder is

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=

This seems to be an error message coming from tcell. You may want to open an issue there to find out if cmder is supported. The tcell repo also includes demos. You can check if you get the same error message there.
