Indeed.

|module SomeUtility
|  def SomeUtility.fancy_format(str)
|    "<text>" + str + "</text>" # these literals are tagged as EUC-JP, right?
|  end
|end
|
|application code in file my_app.rb:
|# -*- coding: UTF-8 -*-
|require 'some_utility'
|puts SomeUtility.fancy_format("an utf8 string")  # this literal is tagged as
|UTF8

I recommend using "ascii" encoding, which is default, for library
files, unless you are sure in what encoding your input data are.
For localization, tools like gettext would help dealing with strings
in the native encoding.
