Yeah, of course font an tool needs to support it. Well ok, maybe we're not yet there. On the other hand, Emacs and Vim are quite old. It works in Kate, Mousepad, Leafpad... Nano does s-t-r-o-k-e too. Geany does a mix where it displays correctly but each char has two strokes, weird. But that is still good enough.
Btw, remember the selector-skandal, where the selectors for which type of conversation the NSA can listen in on RIPE (europes biggest internet exchange point) were waay too broad. They still do that, the illegal act was made legal by Germany later on.
I save it for now, until i work on it again. Possibly the wildcards thing. And that tar includes files of folders given too, from someone else (how to work with that).
But for static storage, only price/kw matters.
