Why not just use unicode characters? This works fine here:

 gnus-summary-line-format "%U%R%z%4L %(%[%-20,20f%]%) %B%s\n" 
 gnus-sum-thread-tree-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 "╰─► "
 gnus-sum-thread-tree-indent "  "
 gnus-sum-thread-tree-false-root "○ "
 gnus-summary-same-subject ""

As long as your font has the necessary characters, AFAIK there should
be no problems.
