Why do you use those macros in math context? Those are no math symbols.
As soon as you remove the change to inline math, all is well, at least
in my setup.

HTH,

Thanks. Removing inline mathematical symbols will solve this problem. But, it seems that this package conflicts with stix package as shown below.

The minimal tex testing document:
```latex
\documentclass{paper}

\usepackage{stix}
\usepackage{dingbat}

\begin{document}

\anchor \eye \Sborder

\end{document}
```
And the error message is shown below:

Hi HT,

that's a typical problem of those packages: There are symbols defined by
both stix and dingbats.

One workaround in this case:

\usepackage{stix}
\let\stixcarriagereturn\carriagereturn
\let\carriagereturn\relax
\usepackage{dingbat}

The second line copies stix' \carriagereturn to a unique macro name so
you can still use it later on. The third line undefines \carriagereturn,
so dingbat can define it again. Thus after the fourth line
\carriagereturn is dingbat's version, and \stixcarriagereturn is stix'
version. If you don't need stix' version, you can omit the second line.

Hope that helps,
Julius Dittmar

Thank you very much for your solution.
