Large curly braces, etc., characters were recommended to be added by the UTC
this past February and were approved by WG2 this past March. They will be
part of Unicode 3.1.

> As far as I see, there are no Unicode characters for building large
> curley braces. Such braces are used in mathematics (for the definition
> of variate functions and in combinatorics) and in music notation
> (grouping of staffs).
> Some parts of these braces can be constructed from the box drawing
> characters U+2502 and U256D-70, but the central parts are lacking.
> These characters are available in groff. If you want to know how the
> glyphs for the central parts look try the following UNIX shell commands:
> echo '\(lk\(rk' | groff -Tps > test.ps
> ghostview test.ps
> Actually, the groff Unicode interface devutf8 maps the right central
> \(rk to U+251D, and the left one \(lk to U+2525. This looks very ugly
> and is not an appatizing for Unicode.
