[iblislin]

well, sorry that my worker generated something weird in /tmp and the test failed.
I removed the problematic file already.

Steps to reproduce:

First, in the shell.

$ touch /path/to/$'\244'$'\270'$'\244'

In REPL:

julia> using REPL.REPLCompletions

julia> test_scomplete(s) = shell_completions(s,lastindex(s))
test_scomplete (generic function with 1 method)

julia> s = "/path/to/"
"/path/to/"

julia> c, r = test_scomplete(s)

[iblislin]

I tried to hit my tab key in REPL in both master and 0.6.3.
The master build gave me exception but 0.6 not.

[KristofferC]

Dup of #25816 I think.

[iblislin]

well, I don't think it's dup.
The REPL raised UTF-8 error in this case.

[KristofferC]

Doesn't seem to happen anymore.
