I am using Linux Libertine and thus far everything has been working flawlessly with regard to the math mode, fonts look very well and match the text perfectly.
However, I found that I do not like the way \overrightarrow is typeset, because the tip of the arrow is very big and touches the letters below. I have found somewhere that the solution to that is to use unicode-math, which is something I should probably do anyways, and turning it on does indeed solve my issue: the arrow changes the tip to something manageable.
The issue is, \setminus disappears; additionally, bold symbols are no longer bold while I do need them for vectors. Therefore, my main question is how can I get a nicer looking arrow without losing \setminus and with working \bm ?
An MWE:
\documentclass{article}
\usepackage{fontspec}
\setmainfont{Linux Libertine}
\usepackage{amsmath}
\usepackage{bm}
\usepackage{unicode-math}
\begin{document}
Overarrow: $\overrightarrow{u, v}$
Setminus: $U\setminus V$
Vector: $x$, $\bm{x}$
\end{document}
EDIT: As @egreg pointed out, the issues with missing \setminus are known. However, even when solved, I need bold symbols in my equations. unicode-math effectively precludes using them, apart from the work-around with FakeBold, see here.
Therefore, is there a way of changing the \overrightarrow without the use of unicode-math?



\renewcommand{\setminus}{\mathbin{\backslash}}doesn't work in my case. Using a single glyph from Asana works, thanks! – Up-and-coming LaTeX Mastah Oct 28 '13 at 19:57libertine, add the packageamssymbthen use\smallsetminus, for some reason with the libertine package smallsetminus closely resembles setminus. – doed Oct 28 '13 at 22:27\mathbf. Please note, I left everything untouched as in your example. I just added theamssymbwith the\smallsetminus. I disagree with egreg's answer in that he chose for you what fonts to have,based in thebmpackage. Of course, regardless of the similarity between the fonts here. – doed Oct 29 '13 at 00:56mathspec, but when I used them I messed something up. I will be adding a follow-up question. – Up-and-coming LaTeX Mastah Oct 29 '13 at 05:24
