canonicalize boolean

When true runs the canonicalize function against the input before encoding.

canonicalize boolean
Default: false

If set to true, canonicalization happens before encoding. If set to false, the given input string will just be encoded.
When this parameter is not specified, canonicalization will not happen. By default, when canonicalization is performed, both mixed and multiple encodings will be allowed.
To use any other combinations you should canonicalize using canonicalize method and then do encoding.
