HTML5 currently maps ⟨ and ⟩ to U+3008 LEFT ANGLE BRACKET, U+3009 RIGHT ANGLE BRACKET, both belonging to `CJK angle brackets' in U+3000--U+303F CJK Symbols and Puntuation. HTML 4.01 maps them to U+2329 LEFT-POINTING ANGLE BRACKET, U+232A RIGHT-POINTING ANGLE BRACKET from `Angle brackets' in the range U+2300--U+23FF Miscellaneous Technical. Unicode 5.0 notes: > These are discouraged for mathematical use because of their > canonical equivalence to CJK punctuation. It would probably be better to use U+27E8 MATHEMATICAL LEFT ANGLE BRACKET, U+27E9 MATHEMATICAL RIGHT ANGLE BRACKET from `Mathematical brackets' in U+27C0--U+27EF Miscellaneous Mathematical Symbols-A, characters that did not yet exist when HTML 4.01 was published. This approach is suggested by http://unicode.org/Public/math/revision-09/MathMap-9.txt: > 27E8; lang; ISOTECH; ** # ⟨ MATHEMATICAL LEFT ANGLE BRACKET > 27E9; rang; ISOTECH; ** # ⟩ MATHEMATICAL RIGHT ANGLE BRACKET Moreover, the (few) browsers I have tested render &lang/&rang, 〈/〉 and ⟨/⟩ identically or simalarly (as "<"/">" in approximative ASCII), whereas 〈/〉 are rendered as full-width East-Asian characters (" <"/" >"). -- ?istein E.
