To follow up on yesterday’s meetup experiments, just installing
`xterm-color` from MELPA isn’t sufficient.  It also needs to be

    (require 'eshell)
    (add-hook 'eshell-before-prompt-hook
              (lambda ()
                (setq xterm-color-preserve-properties t)))
    (add-to-list 'eshell-preoutput-filter-functions 'xterm-color-filter)
    (setq eshell-output-filter-functions
           'eshell-handle-ansi-color eshell-output-filter-functions))

Now the weather is colorful: 🌞

    $ curl wttr.in/berlin

Or, with [white background][2]:

    $ curl wttr.in/berlin?I
