I use xterm too but with `XTerm*faceName: Mono`, which renders the
glyphs properly. As stsp noted, when using utf8, a font capable of
displaying the glyphs is also needed. I can't recall the others I've
used in the past but there have been a couple that also display many
utf8 glyphs nicely. Alternatively, if another font isn't wanted, `export
LC_ALL=C` will use <>, but then the borders will also be drawn with |-.
We might be able to find another pretty glyph that more fonts render
right. I just shared a diff with a different guillemet glyph that might
render with fixed.

Should we perhaps make a note of this in tog(1)? Something to the effect
of:

  If UTF-8 is enabled and some glyphs appear to render incorrectly,
  a more capable font such as Dejavu or Monospace Regular should be
  used.
