Answer 1

You are asking to replace the character "�" but for me that is coming through as three characters 'ï', '¿' and '½'. This might be your problem... If you are using Java prior to Java 1.5 then you only get the UCS-2 characters, that is only the first 65K UTF-8 characters. Based on other comments, it is most likely that the character that you are looking for is '�', that is the Unicode replacement character. This is the character that is "used to replace an incoming character whose value is unknown or unrepresentable in Unicode".

Actually, looking at the comment from Kathy, the other issue that you might be having is that javac is not interpreting your .java file as UTF-8, assuming that you are writing it in UTF-8. Try using:

javac -encoding UTF-8 xx.java

Or, modify your source code to do:

String.replaceAll("\uFFFD", "");
