Note U+276F (❯) is supposed to be a sign a bit like >, not an empty box. 
See attached screenshot.

See, in your settings above, gnus-sum-thread-tree-leaf-with-other is 
actually supposed to be a sign like |--> made up of a few unicode 
characters, the last of which is U+276F, not a "box".

If you genuinely want an actual empty box, like |--[] instead of |-->, I 
suppose you could use one of the several empty-box-looking type unicode 
characters (and make sure you have a font with it in), there's a whole 
bunch of box ones (the below is probably not exhaustive, just some a 
quick visual scan turned up)

U+25A1 ( □ )
U+29E0 ( ⧠ )
U+25AF ( ▯ )
U+2B1C ( ⬜ )
U+2395 ( ⎕ )
U+274F ( ❏ )
U+2610 ( ☐ )
