#789 case-insensitive search for unicode filenames/paths (thx @km-clay!) e2aa8fc ecd18ad
- default-disabled because it is somewhat expensive; enable with global-option srch-icase

download link	is it good?	description
copyparty-sfx.py	✅ the best 👍	runs anywhere! only needs python
copyparty-en.py	✅ also good	same but english-only, no i18n
a docker image	it's ok	good if you prefer docker 🐋
copyparty.exe	⚠️ acceptable	for win8 or later; built-in thumbnailer
u2c.exe	⚠️ acceptable	CLI uploader as a win7+ exe (video)
copyparty.pyz	⚠️ acceptable	similar to the regular sfx, mostly worse
copyparty32.exe	⛔️ dangerous	for win7 -- never expose to the internet!
cpp-winpe64.exe	⛔️ dangerous	runs on 64bit WinPE, otherwise useless
bootable usb	┐(ﾟ∀ﾟ)┌	a surprisingly useful joke (x86_64)
