Special characters not showing properly

[tokoss]

Hi, I bought an addon from serifaddons that uses your PHP @ericmmartin .. It is a contact form. I translated the labels and other UI text to my language (Czech) and it works just fine, I mean, It shows the translated words, sends emails correctly, but it transforms all special characters used in my language (ěščřžýáíé) to the questionmark symbol.. everywhere - on the labels if used, in the email (only in the message field it sends correctly with the spec. char.) I could not figure it out, I tried adding the utf8_encode("..") on each line with label code and then it showed correctly "á" for example, but "š" did not work anyway.. moreover I was not able to apply this to all the parts of the form..

Can you check the code for me please and tell me what is wrong? The Serif support was unable to help me even though I have paid for their addon.. Hopefully you can do more.. I guess it is something with the charset, but I am not experienced enough to figure it out on my own.. The original code without translation is underneath and in the attachment.. The URL I am testing this form is www.onefood.cz/BnB1 where you can see it with translation (the utf8_encode is applied for the labels..)

Thanks!!!!!! PT
