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

Thank you for your advice. Yes, I mean in web browser. I try to add
wm.setCustomHeadElement("<meta charset='ISO-8859-2'>");

But anfortunatelly no change. Diacritic chars not working.

Here is code of webpage. I can't paste it directly.

If I change charset directly in "wm_consts_en.h" everything works properly.

Are you modifying the wm_strings_en.h file?

Not sure if this will work but it's worth a try since I don't have an ESP board beside me.

Try to modify Line 28 in the i18n file (i.e., wm_string_en.h:28 or any self-created i18n file),
the charset in the HTML file was a hardcoded string, adding a custom HTML Head element would not work as you think.

const char WM_LANGUAGE[] PROGMEM = "en-US"; // i18n lang code (you might want to change this to "cs-CZ")

const char HTTP_HEAD_START[]       PROGMEM = "<!DOCTYPE html>"
"<html lang='en'><head>"
"<meta name='format-detection' content='telephone=no'>"
"<meta charset='UTF-8'>" // MODIFY CHARSET HERE, i.e. 'ISO-8859-2'
"<meta  name='viewport' content='width=device-width,initial-scale=1,user-scalable=no'/>"
"<title>{v}</title>";
