Where you gets those symbols, printed by the SFML text class or by the system console?

Do they appear with specific keys or randomly?

Sorry it's not that symbol. It's just a square.

For example, I press ctrl + a and display the character in sf::Text and I see a square.

Ctrl + <letter> produces an ASCII control character (CTRL + A gives the "start of heading" character, ASCII code = 1). Those are not printable and can easily be filtered out with the std::isprint standard function.
