[Win LO4.1.3] All symbols in autocorrect

Hello everyone

My first post here, I'm not used to mailing-lists so please forgive any
use-mistake.

I would like to use several symbols il LO.
I use autocorect a lot, like /^ would do North-East arrow, and \v South-East
arrow.
Unfortunately, I can only choose the "Segoe UI" font in autocorrect "insert
symbol" right-click menu, and SE arrow does not exist in it.
I still can copy-paste from wiki but I would there be some way to access any
ASCII symbol il LO ?

Also, this SE arrow shows wierdly in some fonts (I use Times New Roman),
sometime disapearing (leaving an ugly square), sometimes shrinking.
Is this a known bug ? Is there any workaround ?

As you could see, English is not my native language, so, grammar nazi,
please spare my life.

Thank you very much for help
