I wish you lucks, then.

Not sure it helps, but Verifier.isXMLCharacter(int) from JDOM will check
a character is a valid XML character (this same method is called to
raise the error you got.)

Note it takes an int, not a char, as parameter. This is because it
handles non-BMP characters. You might want to do that too.

Fixed, actually I can reuse API from JDOM to check if character is
valid for XML document, or JDOM text, here is the code samples

            final String tempText;
            final StringBuilder content = new StringBuilder();
            if (item instanceof FileItem)
                tempText = HeadItem.extendedDesc((FileItem) item);
            else
                tempText = item.getDesc();

            /* from JDOM library... */
            /* 159 */int i = 0;
            for (int len = tempText.length(); i < len; ++i)
            /* */{
                /* 161 */final char ch = tempText.charAt(i);
                /* 164 */if (Verifier.isHighSurrogate(ch))
                /* */{
                    /* 166 */++i;
                    /* 167 */if (i < len) {
                        /* 168 */char low = tempText.charAt(i);
                        /* 169 */if (!(Verifier.isLowSurrogate(low))) {
                            /* 170 */continue;
                            /* */}
                        /* */}
                    /* */else {
                        /* 177 */continue;
                        /* */}
                    /* */}
                /* 181 */if (!(Verifier.isXMLCharacter(ch)))
                /* */{
                    /* 185 */continue;
                    /* */}
                /* */content.append(ch);
                /* */}
            /* */
