return value;

Unescape string 
if (value == null || value.length() == 0) {
    return value;
StringBuffer buffer = new StringBuffer();
int pos = 0, max = value.length();

    if (current == '\\' && (pos + 1) < max) {
...
Stringunescape(String x)
This finds any '%xx' and converts to the equivilent char. 
if (x.indexOf('%') < 0) {
    return x;
char[] b = new char[2];
StringBuilder sb = new StringBuilder(x);
for (int pos = 0; pos < sb.length(); pos++) {

    if (c != '%') {
...

int start, end, table_index;
start = escapedText.indexOf("&", index);
if (start > -1) {

    index = start + 1;
    if (end > start) {
        String temp = escapedText.substring(start, end + 1);
        table_index = 0;

    char c = escapedString.charAt(i);
    if (c == '\\') {
        ++i;
        sb.append(unescapeChar(escapedString.charAt(i)));
    } else {
        sb.append(c);
...
StringunescapeString(String iccProfileSrc)
unescape String 
if (iccProfileSrc.startsWith("\"") || iccProfileSrc.startsWith("'")) {
    iccProfileSrc = iccProfileSrc.substring(1);

    if (ch == '\\') {
        i++;
        if (i >= size) {
