Looks like this has been fixed in the man pages for binutils 2.21, whereas Cygwin still uses 2.20. I noticed that when trying it on an install with binutils 2.21 from Cygwin Ports, but you can also see plain old pipe characters being used in 'man i686-pc-mingw32-addr2line' (assuming you've got the mingw-binutils package installed, which also uses 2.21). I don't know exactly what is wrong with those pages, but unlike with HYPHEN vs HYPHEN-MINUS, the CURLY BRACKET EXTENSION certainly is the wrong character to be used there, which is why I don't think this merits a specific workaround in the terminal. Having said that, mintty issue 264 is about dealing with missing line drawing glyphs by either rendering them using graphics primitives or replacing them with approximations, so this one would be a candidate for that. Low priority though. The DejaVu Sans Mono actually does have a glyph for the CURLY BRACKET EXTENSION. Looks rather odd though where those characters are lined up on top of each other in 'man addr2line', because they're as high as the character cell thus forming a continuous line, whereas the pipe character leaves gaps.
