this is the symbol I am looking for, ℉
I don’t remember where I read that °F (° and F) and °C (° and C) are prefered instead of ℉ and ℃.
Anyway, you can choose menu Insert
- Special Character
and type degree in the search box, then you can navigate the font box to find a font that contains these characters. Most fonts only contain the degree (°) symbol.
If you are using English (UK), English (USA) or English (Australia) then AutoCorrect comes already prepopulated with a number of guessable, or at least memorable, corrections. For the degree symbol, simply type :degree:
and it will automatically convert to °
. It takes longer to type than the unicode symbol but it is quicker than opening Special Character and typing degree.
.
You can always create a shorter abbreviation for AutoCorrect.
If you have a character (like your ℉ which you pasted into your question) without leading or trailing whitespace, you can paste it into a Writer document or into a Calc cell and subsequently hit Alt+X. This will show you the unicode in hex. Try it with ℃ (e.g.). A next Alt+X should revert this representation to the character.
