com.ctc.wstx.exc.WstxUnexpectedCharException: Illegal character ((CTRL-CHAR, code 15))

Question

I am extracting data from a XML using the axiom.
But I'm getting above error because of having CTRL-CHAR (eg : â, €, ¢, “, ”, ™, ’, – etc) in the XML.
Can any body help me to replace all the CTRL-SHARs to avoid the above error.

The CTLR-CHAR doesn't refer to those characters you've listed, but to non-printable control characters below U+0020 which (with a few exceptions, notably CR, LF and tab) are not allowed in XML 1.0 documents. If your source documents contain such characters then they're not well-formed XML. — Ian Roberts, Sep 14 '12 at 12:03
@ Ian : Yep, but the exceptions said them as the CTRL-CHAR isn't it? When I simply replace the detected caharacters one after another it works fine. But I need a handy and robust method for this. — ironwood, Sep 14 '12 at 12:07

Currently I'm using following method in this case. But I think there must be a better way than this.

public static String removeNonUtf8CompliantCharacters( final String inString ) {
        if (null == inString ) return null;
        byte[] byteArr = inString.getBytes();
        for ( int i=0; i < byteArr.length; i++ ) {
            byte ch= byteArr[i]; 
            // remove any characters outside the valid UTF-8 range as well as all control characters
            if ( !(ch < 0x00FD && ch > 0x001F) || ch =='&' || ch=='#') {
                byteArr[i]=' ';
            }
        }
        return new String( byteArr );
    }
