Determine Windows codepage -> Ruby Encoding map

This chart has things broken down by Rubys response after calling chcp locally.

  • Invalid codepage means trying to change active codepage on English Windows 2008R2 is broken
  • Ruby failure indicates the inability of Ruby to even load given a codepage (though it did still properly identify the Ruby Encoding)
  • In most cases, Ruby considers the codepage ASCII-8BIT / BINARY
Name Value
710 Invalid codepage
12001 Invalid codepage

Launching puppet via bundle exec with a different encoding / testing scrubbing

  • modify bin/puppet wrapper

    • change #!/usr/bin/env ruby to #!/usr/bin/env ruby -E ISO-8859-1

  • To test the Etc provider on OSX

    • change lib/puppet/provider/user/directoryservice.rb, commenting the line defaultfor :operatingsystem => :darwin
    • change lib/puppet/provider/user/useradd.rb, commenting the line commands :add => "useradd", :delete => "userdel", :modify => "usermod", :password => "chage"

  • To perform some checks, mod lib/puppet/util/character_encoding.rb like:

Comparing ACL on Puppet 4 / Puppet 5

Need to collect

  • Output of puppet resource acl c:\windows
  • Output of test.pp manifest run (make sure c:\test directory is not present prior)
    • What's up with initial application always showing an empty []? (This appears to be a separate bug in all Puppet versions)
file { 'c:/test': ensure => 'directory' } ~>
acl { 'c:/test':
 purge => 'true',
