1. This encoding is not about URLs but filenames.

    Your wording "bastard URL-encoding" is unclear to me, apart from
    that i would much prefer it if you could restrain yourself
    from using pejoratives when doing code reviews.


    However, should "+" for some reason turn out to be an undesireable
    escape character, it can be changed easily.


2. It is not safe to assume that SSIDs contain UTF-8.

    The relevant IEEE standard is botched.


    https://en.wikipedia.org/wiki/Service_set_%28802.11_network%29


    "Note that the 2012 version of the 802.11 standard defines a
    primitive SSIDEncoding, an Enumeration of UNSPECIFIED and UTF-8,
    indicating how the array of octets can be interpreted."


    Imagining how many service sets still operate using the pre-2012
    standard (and/or are botched implementations themselves that fail
    to recognize the issue), i think it is safe to assume that the
    character encoding of an SSID is "UNSPECIFIED" in the general case.


    Therefore, it is handled encoding-agnostic on a byte-per-byte basis,
    and this is what the code accomplishes.


    As i see it, when we have the main concerns of security of the
    installation under control, I will willingly contribute to
    evaluation of a (possible) scan result SSIDEncoding.


Kind regards,
T.
