unescape unicode from input

I am reading line by line from standard input with Scanner, then i print these lines to standard output. But, i need to convert escaped Unicode ch开发者_Python百科aracters like \u00fd to actual character. Is there any way how to do it?

I recommend http://commons.apache.org/lang/api-2.4/org/apache/commons/lang/StringEscapeUtils.html.
