using windows 2008r2 sql server 2012 availability groups bad idea

among issues raises are:

quorum recalculation (a feature of windows failover clustering introduced in windows 2012) numerous bugs requiring windows hotfixes (list in alwayson docs, "stackoverflow patch"), though i'm much less interested in problems fixed bringing deployment date.

he doesn't talk other specifics of why using ags win2008r2 bad idea, other stating alwayson "pushes windows clustering harder other app, , uncovering breaking points". worth noting though supported configuration (alwayson scheme requirements).

what problems have been seen in new deployments using sql server 2012 alwayson availability groups windows server 2008 r2, , these eliminated using windows 2012? there problems seen in windows 2008r2 fixed in windows 2012 not have hotfixes available in 2008r2?

i have worked setting in both windows 2008 , 2012. didnt face much difference between them

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
