Hello,

After migration from Joomla 2.5 to Joomla 3.3.6 lack of Polish characters in tags componentu K2 ver. 2.6.8.
I will add that in the Administrator when you click "save" in the edited article, added tags at once lose their Polish characters

Anyone able to help or to direct?

Hello,

Check under your K2 settings the "Tag System Settings section".
Make sure you have not specified any character replacements.

Field in the replacements of characters is empty.
The problem, unfortunately, is elsewhere

w bazie wszystko na: utf8_general_ci

Generalnie jak w bazie danych edytuję tag i dodam polskie znaki to po zapisaniu jest na stronie i zapleczu ok, tylko jak dodam tag na zapleczu po zapisaniu , znikają polskie znaki

Are you using any SEO/ SEF extensions?

Just seo and sef in component K2


database everything: utf8_general_ci

Generally, as the database I edit the tag and I'll add Polish characters after you save the page and back ok, just as I add a tag in the back after saving, disappear Polish characters

Is the tag normalisation (K2 Settings) option disabled?

Yes that's right.
Thank you for your help :)
