Even though the introduction of Unicode technically solved this problem, you can still encounter situations in which some or all of your Unicode characters will not display properly in Java programs.

You can only represent the ASCII subset of Unicode within the range of a byte. If you wanted to filter one or more Unicode characters from a Java stream, you're hosed!

Character.getNumericValue(aChar) will let me convert a char into an int. I want to know how I can reverse the process and get a char from an integer? Thanks.
