Re: bug in 2nd-highest-upvoted mb_check_encoding() comment code

Unfortunately this is the problem with user contributions. They are
subjective by nature as they may offer up buggy implementation or provide
inaccurate information. While this is true they are ranked by popular vote.
So feel free to down vote if you don't like what you see. However editorial
constraints on user contributions are limited unless they violate a serious
problem such as security, spam, or hate speech.
