I only know using tput to check the info about a terminal. But I have
explicit specific the capname. How can you extract all the information
above a terminal as you did above? Thanks.

$ tput -T dumb cols

I got this. How did you get the more readable format as the above? Thanks.

$ vim -T dumb -c 'echohl ErrorMsg' -c 'echo "Hello World!"' -c q|cat -v
Vim: Warning: Output is not to a terminal
^L^[[78;1HHello World!^M^M

Do you know where I should start? Thanks.
