Unbollox will turn the ASCII into Korean text, but I wouldn't know how to convert the Korean to English.

Those folders/files are actually in Korean, you see them as ASCII because most operating systems don't natively support Korean language. If you did convert every file to English, your client will just error.
tl;dr they aren't supposed to be in English.
Thanks for the CMS, really looks great. Was wondering if it's compatible with FluxCP's rA version? CMS installs fine, but the news feed seems to not appear.
EDIT: Nevermind, fixed it looks and functions amazingly, thanks CalciumKid.
