How can I escape curly braces within the \texttt{} environment?
\texttt{ \{ } produces errors within my template, which can be found here: (link)
I saw this question for square braces, but the solution seems like a bit of a hack, and doesn't work for curly braces.
(FYI, the purpose of this is to include a regex statement in monospaced font, among normal font in the rest of a table. If there's a preferable solution, I'm open to ideas there.)
The problem with \{ and \} is that, if the current font encoding is OT1, the braces will be taken from the symbol font.
You have two strategies:
\documentclass{article}
\begin{document}
$\underbrace{\texttt{\string{c\string}}}$
\end{document}
or the simpler
\documentclass{article}
\usepackage[T1]{fontenc}
\begin{document}
$\underbrace{\texttt{\{c\}}}$
\end{document}
The output is the same (well mostly indistinguishable).
Using curly braces for the source code argument of \lstinline is marked as experimental in the documentation of package listings. The normal form with a character to delimit the argument works without the need to escape braces inside the code:
\documentclass{article}
\usepackage{listings}
\begin{document}
\lstinline|<Button onClick={this.handleClick}>Button component</Button>|
\end{document}
The expression
\lstinline{<Button onClick=\{this.handleClick\}>Button component</Button>}
with or without the backslash does not work, because the source code argument is scanned in a special way as verbatim with changed category codes. The first } ends the argument: <Button onClick=\{this.handleClick\ the remaining part >Button component</Button>} is set outside of \lstinline and the closing curly brace without counterpart causes the error.

For "escaping" one typically use
\, as in\{and\}. However, for the typewriter font, you might be interested in\string{and\string}:\stringprovides similar output to\verb, but is allowed in moving arguments.
