{charcase, upper|lower}

default for decoding: not used
default for encoding: 'upper'

The charcase option specifies the character case to use when encoding unsafe characters as hexadecimal numbers. If the option value is upper characters in the range A-F are used. If the option value is lower characters in the range a-f are used.

{strict, true|false}

default for decoding: 'true'
default for encoding: not used

The strict option speficies the desired behaviour when encountering a percent character not followed by a hexadecimal number. If the option value is true a badarg error is thrown. If the option value is false the percent character is included in the output.

{unsafe, keep|crash}

default for decoding: 'false'
default for encoding: not used

The unsafe option specifies the desired behaviour when encountering an unsafe character in the input while decoding a quoted string. If the option value is keep the unsafe character is included in the output and if the option value is crash a badarg error is thrown.

{plus, true|false}

default for decoding: 'true'
default for encoding: 'false'

The plus option specifies the desired behaviour when encountering a '+' or ' ' character. If the option value is true, '+' is used as an alias for the ' ' character, '+' is decoded as ' ' and ' ' is encoded as '+'. If the option value is false, '+' is decoded as '+' and ' ' is encoded as '%20'.
