literal escape strings in bookmarks

literal escape strings in bookmarks

Below is a simple example of chapter/section titles containing
characters that need to be escaped. Although the page content turns out
correctly, the PDF bookmarks contain the literal escape string instead
or the desired character. Any ideas how avoid this? I guess this is a
bug report.

======

\setupinteraction[state=start]
\placebookmarks[chapter,section]
\starttext
\chapter{test{\char`_}chapter}
The underscore character needs to be escaped in certain situations.
\chapter{start{\char124}stop}
So does the pipe symbol.
\chapter{foo}
\section{bar}
How can I avoid literals escape strings in bookmarks?
\stoptext

there some sanitizing mechanism, but i'm not sure if you wan that here; Why do 
you use the hard coded \char's? If you use the named access mechanisms they are 
normally handled ok in bookmarks

Mostly because I wasn't aware they existed. Your suggestion mostly
works. Unfortunately, I still have a problem with the braces. I'm doing
automated document generation, and I've had problems with stray spaces
finding their way into the document, so I've taken to always using
{\letterbar} or \letterunderscore{}. I suppose I might be able to solve
the problem instead with some creative post-processing, but it'd be
kinda tricky. Any simple solutions?

\setupinteraction[state=start]

\placebookmarks[chapter,section]

\starttext

\chapter{test\getvalue{letterunderscore}chapter}

The underscore character needs to be escaped in certain situations.

\chapter{start\getvalue{letterbar}stop}

So does the pipe symbol.

\chapter{foo}
\section{bar}

\stoptext
