  - escapeJava
```
public static final String escapeJava(String input)
```
    Deprecated.
    Escapes the characters in a String using Java String rules.
    
    Deals correctly with quotes and control-chars (tab, backslash, cr, ff, etc.)
    
    So a tab becomes the characters '\\' and 't'.
    
    The only difference between Java strings and JavaScript strings is that in JavaScript, a single quote and forward-slash (/) are escaped.
    
    Example:
```
 input string: He didn't say, "Stop!"
 output string: He didn't say, \"Stop!\"
 
```
    Parameters:
    
    input - String to escape values in, may be null
    
    Returns:
    
    String with escaped values, null if null string input
  - escapeEcmaScript
```
public static final String escapeEcmaScript(String input)
```
    Deprecated.
    Escapes the characters in a String using EcmaScript String rules.
    
    Escapes any values it finds into their EcmaScript String form. Deals correctly with quotes and control-chars (tab, backslash, cr, ff, etc.)
    
    So a tab becomes the characters '\\' and 't'.
    
    The only difference between Java strings and EcmaScript strings is that in EcmaScript, a single quote and forward-slash (/) are escaped.
    
    Note that EcmaScript is best known by the JavaScript and ActionScript dialects.
    
    Example:
```
 input string: He didn't say, "Stop!"
 output string: He didn\'t say, \"Stop!\"
 
```
    Parameters:
    
    input - String to escape values in, may be null
    
    Returns:
    
    String with escaped values, null if null string input
    
    Since:
    
    3.0
  - escapeJson
```
public static final String escapeJson(String input)
```
    Deprecated.
    Escapes the characters in a String using Json String rules.
    
    Escapes any values it finds into their Json String form. Deals correctly with quotes and control-chars (tab, backslash, cr, ff, etc.)
    
    So a tab becomes the characters '\\' and 't'.
    
    The only difference between Java strings and Json strings is that in Json, forward-slash (/) is escaped.
    
    See http://www.ietf.org/rfc/rfc4627.txt for further details.

    If an entity is unrecognized, it is left alone, and inserted verbatim into the result string. e.g. ">&zzzz;x" will become ">&zzzz;x".
    
    Parameters:
    
    input - the String to unescape, may be null
    
    Returns:
    
    a new unescaped String, null if null string input

    Escapes the characters in a String using XML entities.
    
    For example: "bread" & "butter" => "bread" & "butter".
    
    Supports only the five basic XML entities (gt, lt, quot, amp, apos). Does not support DTDs or external entities.
    
    Note that Unicode characters greater than 0x7f are as of 3.0, no longer escaped. If you still wish this functionality, you can achieve it via the following: StringEscapeUtils.ESCAPE_XML.with( NumericEntityEscaper.between(0x7f, Integer.MAX_VALUE) );
    
    Parameters:
    
    input - the String to escape, may be null

public static String escapeXml10(String input)
```
    Deprecated.
    
    Escapes the characters in a String using XML entities.
    
    For example: "bread" & "butter" => "bread" & "butter".
    
    Note that XML 1.0 is a text-only format: it cannot represent control characters or unpaired Unicode surrogate codepoints, even after escaping. escapeXml10 will remove characters that do not fit in the following ranges:
    
    #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF]
    
    Though not strictly necessary, escapeXml10 will escape characters in the following ranges:
    
    [#x7F-#x84] | [#x86-#x9F]
    
    The returned string can be inserted into a valid XML 1.0 or XML 1.1 document. If you want to allow more non-text characters in an XML 1.1 document, use escapeXml11(String).
    
    Parameters:
    
    input - the String to escape, may be null
    
    Returns:
    
    a new escaped String, null if null string input

    Deprecated.
    
    Escapes the characters in a String using XML entities.
    
    For example: "bread" & "butter" => "bread" & "butter".
    
    XML 1.1 can represent certain control characters, but it cannot represent the null byte or unpaired Unicode surrogate codepoints, even after escaping. escapeXml11 will remove characters that do not fit in the following ranges:
    
    [#x1-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF]
    
    escapeXml11 will escape characters in the following ranges:
    
    [#x1-#x8] | [#xB-#xC] | [#xE-#x1F] | [#x7F-#x84] | [#x86-#x9F]
    
    The returned string can be inserted into a valid XML 1.1 document. Do not use it for XML 1.0 documents.

    input - the String to escape, may be null
    
    Returns:
    
    a new escaped String, null if null string input

    Parameters:
    
    input - the String to unescape, may be null
    
    Returns:

    Parameters:
    
    input - the input CSV column String, may be null

public static final String unescapeCsv(String input)
```
    Deprecated.
    
    Returns a String value for an unescaped CSV column.
    
    If the value is enclosed in double quotes, and contains a comma, newline or double quote, then quotes are removed.
    
    Any double quote escaped characters (a pair of double quotes) are unescaped to just one double quote.
    
    If the value is not enclosed in double quotes, or is and does not contain a comma, newline or double quote, then the String value is returned unchanged.
    see Wikipedia and RFC 4180.
    
    Parameters:
    
    input - the input CSV column String, may be null
    
    Returns:
