Does Unicode affects search bots?

I was wondering if the unicode code in links and text affects ranking and/or indexing on Google or in other search engines; for example, if I write

<a href="http://google.com">Google</a>

Code (markup):

is the same as writing

except that is written on unicode, but browsers display it as normal text (like the first link). So, does it affects?

 

there is no direct relationship of unicode with ranking, so its not affect

 

tanx a lot...even I had the same doubt....!!

 

Google bot sometime not understanding links which contains ? mark as ".asp?id=1".. if the code page is except utf-8..Some time Google report broken links and this is serious issue in ranking also.. So can say Unicode is related to ranking..............
