Check asset encoding for valid UTF-8

utf8check.rb

# 其中包括文件名的非法编码检测以及文件内部非法字符的检测
# 检查特定格式的文件后缀，如css,js可以修改如下：
# Dir.glob(dir_files + "/**.{js,css}").each do |file|.{js,css}

dirstr = "/root/ZTC/"
dir = Dir.new(dirstr)
dir.each do |path|
  next if path == "." || path == ".."
  dir_path = dirstr+path

  if File.exists?(dir_path)
    dir_files = File.join(dir_path, "**")

    Dir.glob(dir_files + "/*").each do |file|
      next if file == dir_files+"/." || path == dir_files+"/.."

      unless file.valid_encoding?
        puts "#{file} name is valid."
      end

      # make sure we're not trying to process a directory
      unless File.directory?(file)
        # read the file and check its encoding
        data = File.read(file)
        unless data.valid_encoding?
          puts "#{ file } does not have valid encoding!"
        end
      end

    end # end Dir.glob

  end #end File.exists
end # end paths.each
