detecting if a text is non-English : What is the most accurate method for detecting if a text (specifically Instagram comments) are non-English? Your code could be in any language prefferably Python, php, etc.

    $ sudo pip2 install guess_language
    >>> from guess_language import guessLanguage
    >>> guessLanguage('la vita e bella')
    'UNKNOWN'
    >>> guessLanguage('today is a good day')
    'UNKNOWN'
    >>> guessLanguage('ボウリング・フォー・コロンバイン(字幕版)')
    'ja'

and with 

    $ sudo apt-get install php5.6-mbstring

          if(strlen($comment->text) == mb_strlen($comment->text, 'utf-8')) {
             echo '- '.$comment->text."\n";
        }


I get many things with English character which are not English:
examples:

    - Khoda be khanevadehashon sabr bede tahamol konan
    - Akhey...
    - Eshghi
    - K

I don't want to use something like Google Translate as I am dealing with lots of data.
