Input Unicode hex values
How do I input a Unicode character using the hex value?
For example, in MS Word, when I type 3007, followed by alt+x, I will get 〇. This is my usual way of typing Unicode characters. I don't have to search. I just type.
How about in LibreOffice Writer? Is it possible to do this? If yes, how? If this is _not_ available, this could be a feature request for future versions of LibreOffice.
