Strange behavior for Japanese characters [segmentation fault]

[minikomi]

Steps to reproduce:

1. Start planck REPL
2. Insert or paste Japanese character - eg, あ - into REPL
3. Press backspace once
4. Press enter

Result:

λ ~ → planck -v
cljs.user=> �
[1]    66037 segmentation fault  planck -v

With the crash fix it now looks like this:

$ ./planck
cljs.user=> ?
#<failed to decode input line>

cljs.user=> 

[minikomi]

Great fast fix 😄
Thanks!

@minikomi FWIW, I tried https://github.com/msteveb/linenoise which is a fork supporting UTF-8, but I couldn't get it to work any differently for entering あ and properly cursoring over it.

Also, you can turn off the readline support in Planck via planck --plain-terminal and even then, in OS X terminal, the ability to delete あ characters doesn't seem to work properly.
