invalid_encoding for no apparent reason

[evokateur]

I installed the gem on two Ubuntu machines and a mac.

I tested with a very simple CSV file

$ cat foo.csv
field1,field2,field3
"hello","hello","hello"

The result on the mac:

$ csvlint foo.csv
..
foo.csv is VALID

The result on both Ubuntu machines:

$ csvlint foo.csv

foo.csv is INVALID
1. invalid_encoding. Row: 1. 1

The encoding of the file:

$ file foo.csv
foo.csv: ASCII text

environments:

• macOS Big Sur, zsh
• Ubuntu 18.04.4 LTS running in Homestead
• Ubuntu 18.04.2 LTS EC2 instance

validation results of the file on csvlint.io

the file:
foo.csv

tried unix2dos, same result in Ubuntu

$ file foo.csv
foo.csv: ASCII text, with CRLF line terminators
$ csvlint foo.csv

foo.csv is INVALID
1. invalid_encoding. Row: 1. 1

Same error for me on Fedora 34 with manually installed csvlint 0.3.3.

This seems to be a problem with ruby3. After switching back to ruby2 (https://blog.kagesenshi.org/2021/05/ruby24-fedora34.html) and upgrading to csvlint 0.4.0 the error vanished.
