I am getting strange issue. When i add string text to some uiComponent which contains special UTF-8 characters like šťčľťťžíľáš element is created correctly and displayed correctly on screen. But only for while. After some time i get something like this:
ObjednĂˇvka dopravy ÄŤ.: 21/243636/4712
exept something like this:
Objednávka dopravy č.: 21/243636/4712
i tried passing string value with UTF-8 charset but no change.
