You can try with the values that were in the comments, and put them in a
conditional statement that checks the host by its platform or its name.

E.g.: 

    (if (eq system-type 'windows-nt)
        (setq gnus-sum-thread-tree-root "> " ; "> "
              gnus-sum-thread-tree-false-root "> "
              gnus-sum-thread-tree-single-indent ""
              gnus-sum-thread-tree-leaf-with-other "+-> "
              gnus-sum-thread-tree-vertical "| "
              gnus-sum-thread-tree-single-leaf "\\-> ")
      (setq ;... the unifont assignment)) ; platforms other than windows

You can make some variants if you want another conditional scheme than
if/else with (cond) or (when), and to test the name of th host you can
test (string-match "\\`foobar" system-name)

HTH.
