Description

10004 $ env -u LANG ruby -U -e 'pp [Encoding.default_internal, Encoding.default_external]'
[#<Encoding:UTF-8>, #<Encoding:US-ASCII>]

10005 $ env -u LANG ruby -EUTF-8 -e 'pp [...]'
[nil, #<Encoding:UTF-8>]

10006 $ env -u LANG ruby -EUTF-8 -U -e 'pp [...]'
[#<Encoding:UTF-8>, #<Encoding:UTF-8>]

10007 $ env -u LANG ruby -EUTF-8:UTF-8 -e 'pp [...]'
[#<Encoding:UTF-8>, #<Encoding:UTF-8>]

10008 $ env -u LANG ruby -UU -e 'pp [...]'
[#<Encoding:UTF-8>, #<Encoding:US-ASCII>]

I think the option processing of encodings is VERY poorly documented and frustrating to try to use.

  1. --help doesn't list -U. (The man page does)
  2. --help for -E doesn't provide a means to get a list of available encoding names (same with manpage), leading me to try U, UTF8, UTF_8, before finding UTF-8. ruby -E could just print them all out.
  3. WHY NOT take UTF8 or UTF_8 (since that's the class name)?
  4. Please consider -UU to mean -EUTF-8:UTF-8
