Setting Default Character Encodings ruby 1.9

[Andrew Barringer]

This is probably something stupid simple I'm overlooking.. but.. here it
goes.

=20

I'm trying to set the default character encoding at the command line
like this:

=20

ruby19 -E ASCII-8BIT:ASCII-8BIT scratch.rb

=20

my scratch.rb file has the following line:

=20

p __ENCODING__

=20

The output is always this:

=20

#<Encoding:US-ASCII>

=20

I want it to be this:

=20

#<Encoding:US-ASCII-8BIT>

=20

What am I doing wrong?

=20

Thanks,

Andy

Hi, this is because -E sets the internal/external encodings. If you
want to set the source encoding, you need to do this with a magic
comment.
If you want ASCII-8BIT, the first line of your source file would look like this:

# encoding: ASCII-8BIT.
