ENCODE{string} -- encode a string to URL entities, HTML entities, CSV format, and more

Line: 18 to 18
type="entity" Encode special characters into HTML entities, like a double quote into ". Does not encode newline (\n) or linefeed (\r). type="url"
extra=" $n$r"
For type="entity" only, use the extra parameter to encode additional characters to HTML numeric entities. Formatting tokens can be used, such as "$n" for newline. Note that type="entity" extra=" $n$r" is equivalent to type="html". type="url"
type="html" Encode special characters into HTML entities. In addition to type="entity", it also encodes space, \n and \r. Useful to encode text properly in HTML input fields. See equivalent ENTITY. type="url"
type="json" Escape double quotes and backslashes with backslashes (\" and \\, respectively), escape non-printable characters with hex code \u0000 ... \u001F, does not change other characters. Use this to properly escape text for a JSON string. Example result: This is a string with \"quoted\" and \\backslashed\\ text. type="url"
type="csv" Escape single quotes and double quotes by repeating them, other characters do not change. Use this to properly escape fields in CSV reports that output comma-separated values, such as "field 1","field 2 with ''single'' and ""double"" quotes". type="url"
newline="..." Replace a newline with the specified value before encoding.
Please note that newline="<br/>" does not bring <br/> to the output because < and > are encoded (except with the quotes and csv types). To have <br/> in the output, you need to specify newline="$br". However, newline="$br" does not work in combination with type="url" (the defautl type). This shouldn't be a problem because it's very rare to need to have <br/> encoded in a URL.
In addition to $br, $n has a special meaning in a newline parameter value - $n results in a newline in the output.
This parameter is expected to be used in combination with the moderate, safe, entity, or html type. With the other types, it causes unuseful results.
