Actually quite a collection of math brackets are currently under ballot and will be included in Unicode 3.2 in the near future: white curly brackets white parentheses z notation image brackets z notation binding brackets square brackets with underbar square brackets with tick in (top/bottom) corners angle brackets with dot black tortoise shell brackets See the online preview of the Unicode 3.2 charts for details: http://www.unicode.org/charts/draftunicode32/ Look in particular at the Miscellaneous Mathematical Symbols-B block. Slightly further out on the horizon, the UTC has voted to disunify some of the CJK brackets, so there will be cloned versions of those appropriate for use in math, as well. And fourteen "hidden" dingbat brackets from the Adobe Zapf Dingbats have been added and are under ballot now, too. So soon there will surely be enough brackets to go around for anybody's proposed syntaxes! --Ken
