invalid byte sequence in UTF-8 (ArgumentError) with ocra

Question

I try to convert a sample ruby script to an executable file with the ocra gem.Here is my ruby script.

puts "Hello word"

Gives me the following error when running ocra test.rb

C:/Ruby31-x64/lib/ruby/gems/3.1.0/gems/ocra-1.3.11/bin/ocra:34:in `tr': invalid byte sequence in UTF-8 (ArgumentError)

        from C:/Ruby31-x64/lib/ruby/gems/3.1.0/gems/ocra-1.3.11/bin/ocra:1231:in `block in <top (required)>'

My version of ruby

ruby -v
ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [x64-mingw-ucrt]

Is there a good way to convert a ruby script to an executable file ?

Answer 1

The issue was my Window username contained the character è. Like Casper mentioned, UFT-8 must be respected with ocra. I followed this link to solve my problem and then restarted ocra and the issue was fixed.
