Hi,
polyglossia documentation states, that babel shorthands ("-shorthands)
are only implemented for German, Dutch and Catalan. This is wrong or at
least misleading as gloss-russian.ldf does indeed invoke
babelshorthands. I'm neither tex-expert nor polyglossia expert, but
lines 29 to 84 from gloss-russian.ldf damn look like babelshorthands to me:
\define@boolkey{russian}[russian@]{babelshorthands}[false]{}
\setkeys{russian}{spelling,numerals}
\ifsystem@babelshorthands
\setkeys{russian}{babelshorthands=true}
\else
\setkeys{russian}{babelshorthands=false}
\fi
\ifcsundef{initiate@active@char}{%
\input{babelsh.def}%
\initiate@active@char{"}%
}{}
\def\russian@shorthands{%
\bbl@activate{"}%
\def\language@group{russian}%
% \declare@shorthand{russian}{"`}{„}%
% \declare@shorthand{russian}{"'}{“}%
% \declare@shorthand{russian}{"<}{«}%
% \declare@shorthand{russian}{">}{»}%
\declare@shorthand{russian}{""}{\hskip\z@skip}%

\declare@shorthand{russian}{"-}{%

\def\@Acdash{\ifdim\lastskip>\z@\unskip\nobreak\hskip.2em\fi
\cyrdash\hskip.2em\ignorespaces}%
\def\@Bcdash{\leavevmode\ifdim\lastskip>\z@\unskip\fi

\declare@shorthand{russian}{",}{\nobreak\hskip.2em\ignorespaces}%
}
\def\norussian@shorthands{%
\@ifundefined{initiate@active@char}{}{\bbl@deactivate{"}}%
}
The real problem seems to be lines 39 to 42, in which babelsh.def is
referenced, which does even more babelshorthand stuff. (probably that's
why it's called babelshORTHANDS.def)
So I commented them out and your minimal example worked with polyglossia
and mathspec.
Concerning mathspec, the problem is the macro \alpha which expands to
"α. The double quotes are mathspecs means to overcome the missing math
metrics in text fonts. It'd probably be better, to implement this
differently, but they at least document it properly.

Hi, Tobias,
I don't need "-shorthands with unicode, but how can I switch them off?

When switching to xetex, I had problems with mathspec and the
"-shorthands as well (I write in German). You should work without
"-shorthands or without mathspec. It's probably easier to work
without mathspec, if you can work with unicode-math instead (saying:
you can use a suitable font).

Dear list members,
I have a problem using mathspec with Greek key together with
polyglossia
with some languages, probably those using " shorthands. Check the
following example (with and without (Greek) or Russian language
selection):
\documentclass{minimal}
\usepackage{mathspec}
\setmathsfont(Digits,Latin,__Greek){Minion Pro}
\usepackage[no-sscript]{__xltxtra}
\usepackage{polyglossia}
\setdefaultlanguage{russian}
\newfontfamily\russianfont{__Minion Pro}
\begin{document}
Проверка: $a+b=\alpha$
\end{document}
Is there any workaround, or mathspec should not be used?
Thank you in advance,
Vadim
