在 XeLaTex 中组合字体

Question

我已经能够组合数学字体，因此

\setmathfont{Asana-Math.otf}
\setmathfont[range={"0370-"03FF}]{GFS Baskerville}
\setmathfont[
   range={"0000-"50,"52-"007F}, % minus ()
   Numbers=Lowercase]           % and use Q from main
   {Adobe Caslon Pro}

但当我尝试使用主字体时

\setmainfont[Numbers=Lowercase, Mapping=tex-text]{Adobe Caslon Pro}
\setmainfont[range={"0041-"007A}]{Wyld}

发生错误

似乎范围选项不适用\setmainfont；但是为什么呢？还有其他方法可以组合两种或多种字体吗？
