Unicode Handling about pathpicker

[pcottle]

yeahhhhh woof there are probably a few things we'll need to do here:

• the first is the most basic -- parse the incoming stdin as utf8 aware and be able to display it correctly
• the second however is the more complex -- regex match against utf8 as well, meaning our regexes need to be updated.

The latter has me worried the most 🙈 maybe @cosbynator can help us since he's mr utf8 regex:

Woot! The latter seems scary to implement. 💩

Cosbynator's regex is used to match emoji, but more characters should be matched to handle unicode filenames. For East Asians, CJK Unified Ideographs is important. It consists of serveral unicode ranges:

• CJK Unified Ideographs: 4E00 to 9FFF
• CJK Unified Ideographs Extension A: 3400 to 4DBF
• CJK Unified Ideographs Extension B: 20000 to 2A6DF
• CJK Unified Ideographs Extension C: 2A700 to 2B73F
• CJK Unified Ideographs Extension D: 2B740 to 2B81F

As a Simplified Chinese users, I think (at least) 4E00 to 9FFF and 3400 to 4DBF should be matched.

Closing this out since I don't think we'll be able to support in anytime soon (and I keep getting nagged by the reap bot), but once almost everyone is on python3 I can add it!
