Apache OpenOffice (AOO) Bugzilla – Issue 39656

Need more symbols and more symbol enhancemens like in ZED

Last modified: 2013-02-07 22:39:09 UTC

1) Need double alphabet symbols like in latex: \mathbb for any symbol. For example I need double S and double V. 2) need more symbols like in ZED formal language. For example there are such symbols in latex (need install zed module into the latext to support the folowing symbols ): \spot (filled circle - very necessary ), \lbag (double [ ), \rbag ( double ]]) , \mapsto (right arrow with foundament in the left ), \dres (empty triangle that points to the left ), \rres (empty triangle that points to the right ), \ndres (striked triangle that points to the left ), \nrres ( striked tirangle that points to the right ). I found there is a zed help book in the Internet: http://www.ual.es/~jjcanada/mfis/practicas/LATEX/zed2e.pdf

Created attachment 20892 [details] The ZED help book; has 13 pages; for this issue interesting are 6 and 7 pages

reassigned to "requirements".

As "divide" sign should also ":" not italic be possible without having to write "nitalic : "

Also I need the double arrow like <-> In latex ZED module it is a command \rel. The best would be if somebody created all the characters desribed in the zed2e.pdf file. May be I could make the symbols? Could anybody tell how to do that, and how to include them into open office math formula editor?

Im working as a maths teacher in germany and here, the symbol for a division is simply a ":" (colon , no dash in the middle). Therefore I will not use the "div" symbol from the formula editor because me students won't understand (at least some of them). I have to use a colon, in the formula editor the colon is always shown with italic attribute so I have to write for every division "a nitalic : b" to get the result "a : b", that I need in my papers at school. I would in common appreceate a larger amount of symbols like in Latex ("double" letters, I think they are called "Fraktur", and also a mapsto-symbol like in Latex).

Is someone working on this issue? I would volunteer, too! The symbols are IMHO a really important step!

Why is this issue not assigned to anybody? Whom can I contact if I awatn to help solving this issue?

OK - I installed Cygwin and Fontforge and I will try to modify the symbol font in a way to get the double alphabet (I think it's called "Euler Fraktur") and most of the symbols explained in "zed2e.pdf". Whom should I contact?

Unfortunately I had no luck in creating an adequate font. Could somebody try to push this one forward to someone that is able to implement the symbols?

Please do not add new fonts with custom encodings. If you want to further math symbol support, check OO.o works well with the STIX fonts (stix.org the beta strangely licensed STIX version is supposed to be replaced by an OFL release soon). If somehow you do not want to depend on STIX submit patches to add the needed symbols to dejavu (dejavu.sf.net) since dejavu is already distributed with OO.o and should already contain many math symbol at the official unicode.org codepoints

Correct weblinks are Stix: http://www.stixfonts.org/ DejaVu Fonts: http://sourceforge.net/projects/dejavu/ The Problem is not the availability of symbol fonts on the net, but the availability of the symbols in the formula editor without much "hand work". So if the symbol font(s) of OO.o will contain more symbols that can then be reached by simply typing a shortcut into the formula editor (like "\mapsto") or by clicking a button in the catalogue, that would solve that issue.

@georgaubele I was refering to your comment of Tue Mar 28 14:46:42 +0000 2006 There is no need to tweak the symbol font anymore since fonts supporting common math symbols already exist and one of them, dejavu, is now bundled with OO.o

Ah ... ok, great! I did not realize, that I have installed new fonts with OO.o 3.0.0 :) So I now start including these fonts into the catalog of the formula editor. http://dejavu.svn.sourceforge.net/viewvc/dejavu/trunk/dejavu-fonts/unicover.txt gives a summery, which symbol is in which font. A more "visual" way of finding the symbols could be achieved by using the freeware "dp4 Font Viewer".

Just be careful that the dejavu in OO.o is not the latest version, so it may have a bit less coverage. I do believe however that if you find significant enhancements in the latest dejavu version you can ask the OO.o dev to update the bundled dejavu for the next OO.o release

I've been to DejaVu website and clicked around to see if there's any list showing what Unicode characters are supported by which DejaVu font but I failed to find such list. However, in STIX website, such list exists and it's easy to find. On the other hand, STIX seems to be a general, human languages-oriented font rather than a mathematics-oriented font like STIX. So I wonder if "adding more math symbols" is the first priority for DejaVu. Well, as a simple user, what I'd really care is whether my math expression is shown or not. I have no interest to get into any font war among OpenSymbol, DejaVu and STIX. It would be nice if they could combine symbols into official font, or drop the font if other fonts have better support (ie they have more symbols).
