如果我使用这个命令：
\documentclass[10pt,amssymb]{revtex4}
\usepackage{amsmath,fontspec}
\setmainfont[Mapping=tex-text}{URW Bookman L}
\begin{document}
Hi man how are u the font is not appearing
\end{document}
我收到此错误：
\par
l.4 \setmainfont[Mapping=tex-text}
{URW Bookman L}
I've run across a `}' that doesn't seem to match anything.
For example, `\def\a#1{...}' and `\a}' would produce
this error. If you simply proceed now, the `\par' that
I've just inserted will cause me to report a runaway
argument that might be the root of the problem. But if
your `}' was spurious, just type `2' and it will go away.
Runaway argument?
Mapping=tex-text
! Paragraph ended before \\setmainfont was complete.
<to be read again>
\par
l.4 \setmainfont[Mapping=tex-text}
{URW Bookman L}
I suspect you've forgotten a `}', causing me to apply this
control sequence to too much text. How can we recover?
My plan is to forget the whole thing and hope for the best.
! Too many }'s.

You've closed more groups than you opened.
Such booboos are generally harmless, so keep going.
! LaTeX Error: Missing \begin{document}.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.

You're in trouble here. Try typing <return> to proceed.
If that doesn't work, type X <return> to quit.

请告诉我应该怎么做？

[为什么用 来关闭打开的内容}？
尝试
\setmainfont[Mapping=tex-text]{URW Bookman L}
反而？
