Just to add the Opera 2 cents into this, we have evangelism activities  
going on around compatibility.  We've known about the EOT issue in  
India for a long time now.  We have had and continue to have success  
in convincing Indian sites to move away from EOT to more open  
equivalents  like switching to UTF-8 encoded content.  IMHO hard work  
and good evangelism works out over bending over backwards supporting  

Couple of quote from our guys:

So, yes there is still work to be done, but it is clear that if there  
is benefit for the sites to change, i.e., only IE supports EOT and  
changing allows Opera/Safari/FF/Chrome to work, then they will change.  
I‘m very willing to discuss with the Safari and Chrome people on how  
we can work together to solve such issues in a optimal way, and pool  
our evangelism resources.
