ruby 1.8.6 puts outputs \000 chars

[John]

I recently updated my gem library, now a simple program outputs \000
chars.
What has changed and is causing the \000 after each char output ?
And how to correct the problem.

Thanks for the help.

----- lister.rb program

t= IO.readlines("gems2.txt")
puts "hello".inspect
puts t[0].inspect #print 1st line of file

--- output from lister.rb

C:\Users\spanton\Documents\GemList>ruby lister.rb
"hello"
"a\000a\000l\000i\000b\000-\000r\000u\000b\000y\000 \000

Is the file system using UTF-16 perhaps?

Hmmmm, my first guess is that the null characters really ARE in the
file "gems2.txt"

perhaps it changed since the last time you ran the program?

As others have said, it looks like your input is UTF-16. Either *treat*
it as UTF-16 or convert it to something else... You *think* you know
what the input file looks like when you view it in some other program,
but that other program is hiding the null bytes from you. They are
really there. m.
