Zig, one of the giants upon whose shoulders this library stands, coined a name for this
    almost-but-not-quite-UTF encoding: WTF-8 and WTF-16. These encodings mean, simply, the
    same as their UTF counterpart but allowing unpaired surrogates to pass through.

To give credit where credit is due, both WTF-8 and WTF-16 were devised by Simon Sapin [1] and Zig simply picked them up.

    sizeof((T){0} = $value)

Wait, is a compound literal an l-value in that sense (as opposed to, just being able to take its reference)?! Take a look at the C99 standard Oh my, it indeed is (C99 §6.5.2.5 p5). Good to know!
