— title: Token not allowed in PDFDocEncoded string category: errors permalink: /FAQ-texorpdf —
The package [`hyperref`](https://ctan.org/pkg/hyperref) produces this error when it doesn't know how to make something into a “character” that will go into one of its PDF entries. For example, the (unlikely) sequence <!– {% raw %} –> ```latex \newcommand{\filled}[2]{%
#1% \hfil #2%
} \section{\filled{foo}{bar}} ``` <!– {% endraw %} –> provokes the error. [`Hyperref`](https://ctan.org/pkg/Hyperref) goes on to tell you: ```latex removing `\hfil' on input line … ``` It's not surprising: how would _you_ put the typesetting instruction `\hfil` into a PDF bookmark?
[`Hyperref`](https://ctan.org/pkg/Hyperref) allows you to define an alternative for such things: the command `\texorpdfstring`, which takes two arguments — the first is what is typeset, the second is what is put into the bookmark. For example, what you would probably like in this case is just a single space in the bookmark; if so, the erroneous example above would become: <!– {% raw %} –> ```latex \newcommand{\filled}[2]{%
#1%
\texorpdfstring{\hfil}{\space}%
#2%
} \section{\filled{foo}{bar}} ``` <!– {% endraw %} –> and with that definition, the example will compile succesfully ([`hyperref`](https://ctan.org/pkg/hyperref) knows about the macro `\space`).
