System Variables
There are a number of variables that have a special meaning.
UTF8 Encoding
You can encode variables values into UTF8 by specifying a UTF8 Encoding parameter.
Example:
$URLTITLE(UTF8)
URL Encoding
Varibles that are part of http:// and https// strings are automatically URL encoded. To remove this encoding, use the
$URL(NONE) syntax.
To force URL encoding on a variable, use the underscore(_) prefix.
Example:
$_URL
$_URLTITLE
$_STATICURL
...
Note: the string to be encoded must start with a http:// or https// for a values to be automatically URL encoded.
