[1.9] Make String#gsub encoding aware for ruby files
----------------------------------------------------
Key: JRUBY-5397
URL: http://jira.codehaus.org/browse/JRUBY-5397
Project: JRuby
Issue Type: Bug
Components: Ruby 1.9
Reporter: David Calavera
Assignee: Thomas E Enebo
Executing this script from a ruby file we raise an error but it should work:
{noformat}
p 'foo'.gsub(/[\x00-\x20%\x7F-\xFF]/, '')
{noformat}
{noformat}
org/jruby/RubyString.java:2843:in `gsub19': invalid multibyte escape:
/[\x00-\x20%\x7F-\xFF]/ (RegexpError)
from org/jruby/RubyString.java:2811:in `gsub19'
from t.rb:3:in `(root)'
{noformat}
Be aware that the same error from the command line or irb is fine because of
the encoding. I guess ruby takes the file encoding from the system and
propagates it to the regular expression.
