Math & Science ⇒ EmptySet

[xgen]

Hello,

I did not use LaTex a long time, so it may have forgotten something
I have MikTex 2.9, LaTex+AmsTex
I can not get a empty set sign using \varnothing
instead of normal empyset sign I have just a "?" on a page
\emptyset works, but I don't like them
maybe I've forgot some package?

Code: Select all

\documentclass[a4paper,12pt]{book}
\usepackage{latexsym}
\usepackage{amsmath,amssymb,amsthm}
\usepackage{amsfonts}
\usepackage{euscript}
\usepackage[T2A]{fontenc}
\usepackage[cp1251]{inputenc}
\usepackage[russian]{babel}

First: Welcome to the LaTeX Community!

If I compile the following code using pdflatex, I get the attached output:

Code: Select all

\documentclass[a4paper,12pt]{book}

\usepackage[russian]{babel}
\usepackage[cp1251]{inputenc}
\usepackage[T2A]{fontenc}
\usepackage{amsfonts}
\usepackage{amsmath,amssymb,amsthm}
\usepackage{latexsym}
\usepackage{euscript}

\begin{document}
$\varnothing$
\end{document}

Comments:

* Please provide a minimal working example next time.
* It is a good idea to load babel, inputenc, and fontenc as the first three packages, in the mentioned order.
* It is often a good idea to pass options to the document class; they are then applied to all possible packages. In this case, I would use

Code: Select all

\documentclass[a4paper,12pt,russian]{book}

\usepackage{babel}

Thanks a lot,

a couple of hours of night work - the problem is not in LaTex or AmsTex,
I have a same pdf file using pdflatex, but
problem is in dvi viwer YaP:
font msbm10 is missing

how can I get it?

No idea but why not compile with pdflatex and view the PDF file (with Foxit Reader in Windows or, e.g., Evince in Linux)?

Update
It seems that you can get it from CTAN: http://www.ctan.org/tex-archive/fonts/c ... akoma/ttf/

I don't know how, but I've found missing font

This is not quite true. One should load »fontenc« before »inputenc« (and both are unnecessary when using XeLaTeX od LuaLaTeX but that's another story). I was unable to find the reference I base my claim on, though What I do have is a nice summary of both packages: fontenc vs inputenc.

Best

True. I simply switch the two packages.

Thanks for pointing it out.
