- hnuser123456 2y agoWow. Did not expect you can just hide arbitrary data inside totally normal looking strings like that. If I select up to "Copy thi" and decode, there's no hidden string, but just holding shift+right arrow to select just "one more character", the "s" in "this", the hidden string comes along.
- Izkata 2y agoBased on vim's word wrapping (which shows blank spaces instead of completely hiding it), they're being rendered at the end of the line. So if that is accurate it kind of makes sense that for UI-based interactions to be a one-character offset.
- n2d4 2y ago> Is this necessary to correctly represent human language? Yes! As soon as you have any invisible characters (eg. RTL or LTR marks, which are required to represent human language), you will be able to encode any data you want.
- wruza 2y agoHow many direction marks can we see in this hidden text?
- n2d4 2y agoNone — it's tag characters instead, which are used to represent emojis. But there's no difference! Either you can smuggle text in Unicode, or you can't. It's quite binary, and you don't gain advantages from having "fewer ways" to smuggle text, but you certainly gain advantages from having emojis in your characterset.
- wruza 2y agoThis yesman attitude is honestly unnerving. We make things worse, because they were worse! Sort of not, but were anyway. That’s an advantage, nothing to see here! Instead of praising the advantages of going insane, let us better make (or at least strive for) a charset that makes subj work in practice, not on paper.
