Character Palette doesn't have logic symbols

[titusjewell]

I am unable to use open office for my logic classes since it is missing certain important characters. Open office doesn't have existential quantifier symbols (an upside down A and a backwards E). It also doesn't have a horseshoe.

How can I fix open office so that I can type up my logic notes? Is it possible to fix or should I just scrap the whole program and use microsoft office?

I am also unable to use the aleph symbol since it causes the cursor to move in the wrong direction.

Conclusion: Open office is not math and logic friendly. Please help.

Hi and welcome to the forums.

Happily, that's the wrong conclusion. Check out Chapter 16 of the Writer's guide. OpenOffice.org 3 User Guides.

The best way is to use formula boxes, as described in TheGurkha’s link. However, if you want to use these characters in ‘normal’ text, you should use Insert > Special Characters…, notice that you need the “Mathematical Operators” subset, also, not every font supports these characters.

As for the א-function: א is a Hebrew character, it is supposed to be written from right to left, which probably is the “wrong” direction to you; I am not sure if, in ‘normal’ text, there is an א character that does not show this behaviour, maybe it is in the Mathematical Operators subset of the Special Characters table.

You put a dead link. Here's an idea - why not just tell us how to do it!!!!!

[Robert Tucker]

My link? I just tried it and it worked. U+2135 is stated to be the correct character here: https://www.johndcook.com/blog/math-symbols/

You will need to find out the easiest way to enter a character by its code point on your operating system and maybe set a shortcut to it.

It is a 10 year old topic.
Maybe some links are dead today, but the OOo 3.x versions are dead too.
Use the AOO 4.x or the LibreOffice 6.x.


You can write a macro to put unicode special characters into a document, or you can use the Autocorrect feature.
Search and apply the codes of a public Unicode table - from the internet.

Link working fine for me.

It's not an AOO problem - it is a problem with the fonts you have (or, in this case, have not) installed.

1. Download a font which contains the symbols you want to use - eg see Math Symbol

2. Install the font.

3. Restart AOO

Bingo! all the symbols in that font are available in AOO. You probably need to use Insert > Special Character ..., to insert them.

Also see the Math module of AOO.
