```
public static String escapeXMLCharacters(String input)

```
public static String replaceInvalidXmlCharacters(String text)
```
    Take a String which may contain characters outside of the XML character range (http://www.w3.org/TR/REC-xml/#charsets) and return a String with those characters converted to Unicode "Replacement Character"s (0xFFFD). Note that this method does not "escape" the string (e.g. "&" is not converted to "&"). Similar to Verifier.checkCharacterData(String) but converts illegals instead of throwing Exceptions.
    
    Parameters:
    text - the input string
    
    Returns:
    the input string with those characters converted to Unicode "Replacement Character"s
  - htmlEscapeQuotes

    Take a string and escape the quotes in it with \" and HTML escape them afterwards. We need this function to escape strings containing quotes passed into JavaScript functions null input will be returned as an empty String.
    
    Parameters:
    input - string to escape
    
    Returns:
    the escaped string

```
public static String shortenString(String str,
                   int max)

    Parameters:
    str - the string to shorten
    max - the maximum desired length of the result (excluding ELLIPSIS)
    
    Returns:
    a substring of the specified string if it is longer than max.

  - specialToLowerCase
```
public static String specialToLowerCase(String str)
```
    the database lower() function in PostgreSQL only works for ASCII strings. All other unicode and multibyte characters like capital umlaut are not properly converted. At the moment, when searching for pages we do the following comparison:
    
    lower(page.title) = :pageTitle (Where :pageTitle is normally .toLowerCase() first before being passed in)
    
    This special lower case function will skip the JAVA .toLowerCase() for postgres whose database lower() is ineffective.
    
    Parameters:
    str - the string to convert to lower case
    
    Returns:
    the lower cased string
