\textsc 在带有装饰的路径上

Question

[原始问题]

\documentclass[tikz,border=5pt]{standalone}
\usetikzlibrary{decorations.text}    
\begin{document}
\begin{tikzpicture}  
    \node [circle, draw=red, fill=red!30] (N1) at (0,0) {A};
  \node [circle, draw=red, fill=green!30] (N2) at (5,0) {B};
  \draw [red,->] [postaction={decoration={raise=3pt, text along path, text={|\textsc|Text||},text align=center}, decorate}] (N1.north) to [out=45,in=135] (N2.north);
\end{tikzpicture}
\end{document}

我想要\textsc作品。有什么帮助吗？

[更新]

听了 CarLaTeX 的回答后，我得到了：

\documentclass[tikz,border=5pt]{standalone}
\usetikzlibrary{decorations.text}    
\begin{document}
\begin{tikzpicture}  
    \node [circle, draw=red, fill=red!30] (N1) at (0,0) {A};
  \node [circle, draw=red, fill=green!30] (N2) at (5,0) {B};
  \draw [red,->] [postaction={decoration={raise=3pt, text along path, text={|\scshape|Text |\_| |+$\theta$|},text align=center}, decorate}] (N1.north) to [out=45,in=135] (N2.north);
\end{tikzpicture}
\end{document}

我想要_并且$\theta$有效。

我认为你必须使用\scshape：

\documentclass[tikz,border=5pt]{standalone}
\usetikzlibrary{decorations.text}    

\begin{document}
\begin{tikzpicture}  
  \node [circle, draw=red, fill=red!30] (N1) at (0,0) {A};
  \node [circle, draw=red, fill=green!30] (N2) at (5,0) {B};
  \draw [red,->] [postaction={decoration={raise=3pt, text along path, text={|\scshape|text},text align=center}, decorate}] (N1.north) to [out=45,in=135] (N2.north);
\end{tikzpicture}
\end{document}

把它们放入{...}：

\documentclass[tikz,border=5pt]{standalone} 
\usetikzlibrary{decorations.text} 
\begin{document}
\begin{tikzpicture} 
\node [circle, draw=red, fill=red!30] (N1) at (0,0) {A}; 
\node [circle, draw=red, fill=green!30] (N2) at (5,0) {B}; 
\draw [red,->] [postaction={decoration={raise=3pt, text along path, text={|\scshape|text {\_ $\theta$}},text align=center}, decorate}] (N1.north) to [out=45,in=135] (N2.north); \end{tikzpicture} 
\end{document}
