Summary: FORMULAEDITOR: Formula editor symbols catalog has a
lot of important greek letters missing
Severity: normal
Classification: Unclassified
OS: Windows (All)
Reporter: [email protected]
Hardware: Other
Whiteboard: BSA
Status: UNCONFIRMED
Version: 4.3.1.2 release
Component: Formula Editor
Product: LibreOffice
Created attachment 105642
--> https://bugs.freedesktop.org/attachment.cgi?id=105642&action=edit
A presentation showning formula corruption in three comparative examples on
page 1, and comparing the lists of Greek lowercase letters in LO 4.3.2 (wrong)
and OO 4.01 (correct)
Problem description:
In the formula editor, the "Catalog" allowed you to insert easily any greek
letter into your formula, as well as other symbols. In 4.3.1 most lowercase
Greek letter are gone, among them some of the most important ones. The
lowercase sigma, for example, the symbol universally used for standard
deviation, is no more. You can add it manually to the catalog, just as you
could do with a dozen other lowercase Greek letters missing. This is no real
solution, however; if you insert your newly created symbol, e.g. "sigma", when
you reopen the formula "sigma" in the code will be automatically turned into
"SIGMA" and in the formula output you will have the capital sigma Greek letter
instead of the lowercase.
Non of this happened before, tough I am not able to tell exactly which release
was the first to have this problem.
This is a really huge problem: if you write a lot of formulas Libreoffice is
basically unusable at present. Moreover, another danger lies in the fact that
any old document in which you reopen existing formulas for editing will have
them corrupted.
Steps to reproduce:
1. open the attached presentation file. the first formula was written with an
old well behaving version, and is correct.
2. the second formula was a copy of the first, which was opened with 4.3.2. As
you can see the sigma e rho lowercase symbols were turned into capital letter,
fully inappropriate here.
3. open the catalog, choose "edit" button and add two "new symbols named
"sigma" and "rho". Then n the third formula, which was a copy of the second
one, rewriting manually "sigma" and "rho" in lowercase replacing the capital
letter codes gives you the correct symbols in the output. BUT: if you edit the
formula again, they will automatically be turned into uppercase again!
Current behavior:
At present it is practically impossible to do any math editing if you make
large use of greek letters (i.e. very often)
Expected behavior:
symbols catalog should take
Operating System: Windows 7
Version: 4.3.1.2 release
