Setting Default Character Encodings ruby 1.9

Ruby
#1

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

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

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

my scratch.rb file has the following line:

p ENCODING

The output is always this:

#Encoding:US-ASCII

I want it to be this:

#Encoding:US-ASCII-8BIT

What am I doing wrong?

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.
