When you need to parse some text files - you need to be sure, that they are in some particular encoding before actually parsing them. For example, some symbols are invalid for UTF-8 encoding, but nevertheless files which are mainly in UTF-8 can contain some invalid characters and many of editors will not show you that. This gem will help you identify lines and characters of the text which are invalid for particular encoding.
This gem relies on encoding information, which is available only in Ruby 1.9.x. Maybe sometimes I'll add 1.8.x support through iconv library, but for now 1.8.x is not supported.
Add this line to your application's Gemfile:
gem 'encoding_checker'
And then execute:
$ bundle
Or install it yourself as:
$ gem install encoding_checker
# instantiate checker with encoding name
checker = EncodingChecker.new("utf-8")
# check any particular text
result = checker.check("some string with wrong\xA0symbol")
unless result.empty?
result.invalid_lines.each do |line|
# use line.content, line.index and line.invalid_characters
line.invalid_characters.each do |character|
# use character.content and character.index
end
end
end
# raises EncodingChecker::Error
checker.check!("some string with wrong\xA0symbol")
