Fatal error: exception LTerm.No_such_encoding("646")

[UnixJunkie]

Hello,

While trying to run utop on NetBSD:

Fatal error: exception LTerm.No_such_encoding("646")
Raised at file "src/lTerm.ml", line 163, characters 10-33

I wonder if the same thing happens on OpenBSD.

utop version 2.3.0 and OCaml 4.07.1

Thanks,
F.

A command that returns 646:

locale charmap

[UnixJunkie]

A workaround is adding those lines to ~/.bashrc:

export LANG="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
export LC_ALL=""

I am closing; if you think this is really a bug, you can reopen.

The code name can be ISO_646.BASIC or ISO_646.IRV, IIRC
