!Joomlacomment is working on a lot of websites, all with different languages. We have chinease, korean, russian, german and ... installations. A small problem we had with 3.26 was that we were using not utf8 aware functions - so on some sites that were using the feature under content settigns->security -> overflow there were sometimes problems with "funny" characters like these ones 'äöüßщюпчюпоиеявш' :)
I was thinking that I fixed this bug with alpha2, but today I saw that on our demo section we had problems with one language. Looking for the problem, I found ouт that it was the wordwrap function that is not utf8 aware. Reading the comments here I copied a function from Golan Zakai and now I believe our extension is fully utf8 compatible!
Furthermore, I stopped using the mb_substr and mb_strlen functions and started using Joomla's JString class. This should save us from problems like this one here.
The first beta is nearly ready! Stay tuned!
