@lunny, I'd recommend to simplify the charset package test or even remove it. It's still failing randomly, presumably because of different settings on each server. After all this time I guess they make not much sense, as the "golang.org/x/net/html/charset" functions seem to fail only when memory is very short. Comparing conversions between invalid strings was a bad idea from my part. 😳

What do you think?

It seems this is unnecessary. Just close this.
