How do I determine the unicode of a character in LibreOffice?

Hi,
I know how to insert Unicode values in LibreOffice Writer, but is there a way to find out which Unicode has been used to enter a character that is already there (ie. in someone else’s text)?
Thanks! Renee

Thank you Mike, sorry I didn’t catch this earlier.

Use Alt+X.

Thanks Mike, I think the problem is that I am using the Dutch version in which Alt-X is the shortcut for the Extra tab.

The link that I posted contains detailed procedure how to assign any shortcut to it, and also about special assignment in your locale - please read carefully:

Alt+C used for Basque/Dutch/Galician/German/Brazilian-Portugese locales

Aside: please don’t use “Answer” for what is not an answer to (your) original question - comments are for that.
