I am a member of Stack Overflow in Portuguese, I cross-posted the exact same question on both sites:
On Stack Overflow
The first thing that happened was a useless comment asking why followed by a suggestion of a full library to use a single method that I asked and this library doesn't even do what I asked.
Another member came and suggested two libraries (which I don't want a full library for a single method) and neither libraries do what I want.
I've being trying to implement and I posted as an answer what I managed. Even though it is not really fast, it works pretty well.
I instantly got a downvote, the person that downvoted didn't even test or tried to understand what I tried for hours.

Also I've never had the intent to make it sound like SO PT is better than SO, if anyone thought that. It's just that SO PT was a new community, fresh, and people were being nice because of it.
