+-- Notice for opening non-ASCII 7bit filename
+If you'll plan to open the non-ascii character named file by Java class through Rjb, it may require to set LC_ALL environment variable in you sciprt.
+For example in Rails, set above line in production.rb as your environment.
+ENV['LC_ALL'] = 'en_us.utf8' # or ja_JP.utf8 etc.
