   What is the rationale for this? I can understand changing mapping  
for &lang; from U+2329 to U+3008, because it's the new code point for  
the same character (and that's what we did in WebKit), but changing it  
to an entirely different character seems weird, and bad for  
compatibility.

   Besides, font support for U+027E8 MATHEMATICAL LEFT ANGLE BRACKET  
seems to be rather poor at the moment - on my machine, there is only  
one font that has it.
