Encoding/Decoding within URLs: * * The following two functions perform the '%'-substitution for * characters that may otherwise be interpreted as metacharacters. * * According to: RFC 1738, RFC 1630 * * Option plus: This option has been added because there are some * implementations that do not map ' ' to '+', for example Javascript's * escape function. The default is true because this is the RFC- * compliant definition.
There are no tstring and polymorphic versions of the encode and decode functions, as URLs are comparatively short, and it is considered as acceptable for the user to convert types as needed, even if strings need to be copied for that.
Option plus: Whether '+' is converted to space. The default * is true. If false, '+' is returned as it is. * * The optional arguments pos and len may restrict the string * to process to this substring.
Option plus: Whether spaces are converted to '+'. The default * is true. If false, spaces are converted to "%20", and * only %xx sequences are produced.
