Change default charset UTF-8

Is it possible change default charset from UTF-8 to ISO-8859-2? I use this encodig in VS Code (because encoding chars for external display).
I would like to get some texts from WiFi portal to ESP32 and there is some problems with decoding letters á, č, ď, é, ě, í, ň, ó, ř, š, ť, ú, ů, ý, ž, Á, Č, Ď, É, Ě, Í, Ň, Ó, Ř, Š, Ť, Ú, Ů, Ý, Ž

ThankYou
