That's strange.  Is util._use_dec_special set to False on your system? 
It should be True, and that should cause \u2502 to map to '\x0fx\x0e' .. 
which should have no problem being "encoded" in latin-1.

Would you change util.py line 104 to:
		try:
			s = s.encode( _target_encoding )
		except UnicodeError:
			assert 0, `_use_dec_special, s`
and post the output?
