FunC #include: failed to load "�.fc"

[cornobils]

When I try to run #include "stdlib.fc", I have this error in console: failed to load "�.fc". Also when I try enter full path to the .fc file, I receive failed to load "�dmitry/Coding/ton/ton/crypto/smartcont/stdlib.fc".

.zshrc looks like this:

export FUNCPATH=/home/dmitry/Coding/ton/ton/crypto/smartcont:/home/dmitry/Coding/ton/ton/build/crypto

Tried also with $HOME instead of full home directories. Fift kernel with example commands from repository readme looks like are working. Kubuntu 19.10, .deb install, tried versions 0.2.5 and 0.2.1. In Jupyter about window I have Python 3.7.5, notebook version 6.0.2
