Cute. But presupposing that the OP isn't the idiot some people seem to 
have assumed, I suspect he meant something more like

   String line = someBufferedFile.readline();
   ... change all \u escapes into unicode in "line" ... [1]

where by "\u escapes" he mean the 6-character substrings one usually 
types in string literals. The OP needs to look into "code points" and 
the corresponding codepoint to Character conversions at
http://docs.oracle.com/javase/7/docs/api/java/lang/Character.html

[1] which, for the pedantic, really means "create a new string(buffer) 
from line"
