asn2wrs script failure on Wireshark release 3.0.1, Python 2.7.15rc1 on Ubuntu

Hello,
This is about exception while running Python asn2wrs script to generate
dissector for ASN.1 files.
I tried to debug it, but I failed :(
Note that ASN.1 files contain parmaterized types.
The exception is:
vagrant@ubuntu1804:~/frameworks/wireshark-gerrit-20190419-dev/epan/dissectors/asn1/ieee1609dot2$
./asn2wrs.sh
ASN.1 to Wireshark dissector compiler
:0: UserWarning: Decoding ./EtsiTs102941TypesAuthorization.asn as utf-8 failed,
trying next.
