For a blinking cursor/insertion point/caret you can use rectangle shape and a clock to time it, but you need to be specific with what you need help. :)

Yes, caret.

I meant if you have already tried to implement it, and if there has been a specific problem.

Generally, look at the sf::Text and sf::Glyph classes. With them, you can find out the width of single characters. By comparing the character position with the mouse position, you know where the caret is placed. It requires some thinking, but it shouldn't be extremely difficult.

Can I just use sf::Text::getGlobalBound or getLocalBound to get width and height?

No, getGlobalBounds() only yields the position of the text's bounding rectangle. You are interested in the positions and sizes of the single characters in the text object.
