Hi folks,

did someone of you experience this as well?

$ uname -a
CYGWIN_NT-6.1 arnie 1.7.32(0.274/5/3) 2014-08-13 23:06 x86_64 Cygwin
$ ruby --version
ruby 2.0.0p481 (2014-05-08) [x86_64-cygwin]
$ gem --version
2.4.1
$ gem list -l

$ gem update

Apparently when reading a file the environment's encoding information
is applied. I'm just not sure whether this is an issue with gem
command or a Cygwin adjustment to that.

Bonus points for a solution. :-)

Kind regards

robert
