Fatal error: exception LTerm.No_such_encoding("646") #303

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
Called from file "src/lTerm.ml", line 197, characters 6-301

I wonder if the same thing happens on OpenBSD.

utop version 2.3.0 and OCaml 4.07.1

Thanks, F.

Do you think you can try to track down what is occurring? It's much easier for you given that you have a setup that will reproduce the problem.

the bug should probably be moved to lambda-term
