Aleksa Sarai	de223ffc92	unvis: implement meta and ctrl characters ('\M__' and '\^_') ... While these characters are really weird to handle, here is a fairly simple implementation that need some more testing (and a proper secondary source to compare against).

Aleksa Sarai	35708696fe	unvis: implement proper '\xff' and '\377' escape handling ... In particular, previously such escape handling would break because we would attempt to encode characters >0x7f as runes -- which would then result in escapes that want to encode multi-byte characters breaking. There's still some work necessary in Vis() to make it act sanely when it comes to arbitrary bit streams. Not to mention that we need to figure out what we actually want to do there...

Aleksa Sarai	cd1de45ba5	unvis: implement partial unvis(3) implementation ... Also add some unit tests -- one of which currently fails due to ongoing design discussion about how certain escape codes should be handled. Signed-off-by: Aleksa Sarai <asarai@suse.de>	2017-02-12 04:06:25 +11:00
