Truncate Text But in Backward Direction in Django

I have myString = "Get the last nine characters of this text, starting with the last one." and I want to be able to get the last nine characters of in Django template the way I could get the first nine with {{ myString|truncatechars:9 }}.

Any idea on how I can get this done?

You can write your own filters. 

@register.filter("truncate_chars")
def truncate_chars(value, max_length):
    if len(value) > max_length:
        #will return last characters if max_length<0
        truncd_val = value[max_length:]
        if not len(value) == max_length+1 and value[max_length+1] != " ":
            truncd_val = truncd_val[:truncd_val.rfind(" ")]
        return  truncd_val + "..."
    return value

and then 

{{ myString|truncate_chars:-9 }}

Look at here.
