Slovakian characters in smartforms

Hi experts,

I'd like to use Slovakian characters in my smartforms like Č/č. Everything works fine, if I edit the smartform in SK language. But if I create a form in EN language, and try to write Č/č characters I get É/é characters.

I read the topic in SCN, but every post talks about the printing. In my case the problem is before the printing, the smartform itself has wrong characters.

The system is an Unicode system (SCP_GET_CODEPAGE_KIND returns 'U2L')

Is it posible to get correct Slovakian characters evenon an English form? If yes then how?

Please help

Thanks & Kind regards

Nándor
