Hi all,
If I compile this file:
\documentclass{article}
\usepackage{fontspec}
\usepackage{xltxtra}
\usepackage{unicode-math}
\begin{document}
$P'$
\end{document}
I get this error message:
! Undefined control sequence.
<argument> \um_prime_single_mchar
l.6 $P'$
Why is that? The unicode-math documentation says:
In regular LATEX, primes can be entered with the straight quote
character ', and multiple straight quotes chain together to produce
multiple primes. [...] For Unicode maths, we wish to conserve this
behaviour.
Therefore, I don't see why this happens.
If, instead of the straight quote character ' I use a prime ′, then I
get no error message, but I get:
Missing character: There is no ′ in font cmr10!
What should I do in order to get the prime?
Best regards,
José Carlos Santos
