Redmine

there is no problem when attach files to issue in the brower.
However, if the issue is created via incoming email, the attached file name can not be displayed correctly if they
are chinese.
For example, I got something like GB2312_B_RGF0YXN0YWdlOC4xyf28trLiytS94bn7Lnhscw__ .
It seems to me an encoding problem. From above I guess the original file name was encoded via GB2312, but the mysql database is utf8.
I read the code, is it the place that extra the filename of the attachment.

  def sanitize_filename(value)
    # get only the filename, not the whole path
    just_filename = value.gsub(/^.*(\\|\/)/, '')
    # NOTE: File.basename doesn't work right with Windows paths on Unix
    # INCORRECT: just_filename = File.basename(value.gsub('\\\\', '/')) 

    # Finally, replace all non alphanumeric, hyphens or periods with underscore
    @filename = just_filename.gsub(/[^\w\.\-]/,'_') 
  end

Any help is appreicated!
