} else {
    return unescape(string, 0, length);
Stringunquote(String string, char quote)

if (string.length() >= 2 && string.charAt(0) == quote && string.charAt(string.length() - 1) == quote)
    return string.substring(1, string.length() - 1);
else
    return string;
Stringunquote(String text)
unquote 
if (text.length() > 0 && text.charAt(0) == SINGLE_QUOTE && text.charAt(text.length() - 1) == SINGLE_QUOTE) {

return text;
Stringunquote(String text)
unquote 
if (text.startsWith("\"") && text.endsWith("\"")) {
