Julia 0.7.0-alpha.0 ERROR: PCRE.exec error: UTF-8 error: isolated byte with 0x80 bit set

Have you tried setting the LC_TIME locale field to <whatever_your_language_is>.UTF-8?

You could do that directly in your ~/.juliarc.jl file.

See the discussion here: Strftime & strptime bug #27239 is present on all platforms, not just Windows - #3 by ScottPJones

You could use this code to set the locale for Julia to whatever your language is, but using UTF-8:

julia> setlocale(lc) = unsafe_string(ccall((:setlocale,"libc"), Cstring,(Cint,Cstring),0,lc))
setlocale (generic function with 1 method)
julia> setlocale("ko_KR.UTF-8")
"ko_KR.UTF-8"
