How to get unicode to be typed through sf::TextEntered

[codinglexernewbie]

I want to be able to get Unicode letters e.g: ∏ by typing alt + 8719 like possible in Wordpad, but it doesn't seem to work using the default instead it turns into ☼(15), why does it reset after 256?, and is there a way to do what I want in the standard lib?

Unicode is complicated - see this post: https://stackoverflow.com/a/50407375/6740859

Broadly speaking std::string is mostly compatible with utf-8 but you may need to convert to/from codepoints when used with sf::String. In my experience I've found it best to try and stick to a unicode aware string class (like sf::String which is, admittedly, not the standard library but supports full 32 bit characters) and only convert when necessary, such as reading or writing a text file.
