Character issues like this are difficult to diagnose because information is easily lost through misinterpretation of characters via application bugs, misconfiguration, cut'n'paste, etc.

As I (and apparently others) see it, you've pasted three characters:

codepoint   glyph   escaped    windows-1252    info
=======================================================================
U+00ef      ï       \u00ef     ef,             LATIN_1_SUPPLEMENT, LOWERCASE_LETTER
U+00bf      ¿       \u00bf     bf,             LATIN_1_SUPPLEMENT, OTHER_PUNCTUATION
U+00bd      ½       \u00bd     bd,             LATIN_1_SUPPLEMENT, OTHER_NUMBER

To identify the character, download and run the program from this page. Paste your character into the text field and select the glyph mode; paste the report into your question. It'll help people identify the problematic character.

As others have said  you posted 3 characters instead of one  I suggest you run this little snippet of code to see what s actually in your string   public static void dumpString String text        for  int i 0  i  lt  text length    i                  System out println  U     Integer toString text charAt i   16                                      text charAt i              If you post the results of that  it ll be easier to work out what s going on   I haven t bothered padding the string - we can do that by inspection

You are asking to replace the character     but for me that is coming through as three characters            and       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

Change the Encoding to UTF-8 while parsing  This will remove the special characters

User · Answer

Use the unicode escape sequence  First you ll have to find the codepoint for the character you seek to replace  let s just say it is ABCD in hex    str   str replaceAll   uABCD
