Missing character: There is no c in font nullfont!

[nilesjohnson]

There are some missing character warnings with the new tikz library. I know they can be ignored, but they make it harder to find all the other problems with my tex documents :/

Example input:

\documentclass{minimal}

\usepackage{tikz}
\usetikzlibrary{
  braids,
  arrows.meta
}

\begin{document}

\begin{tikzpicture}[ultra thick]
\pic[
  rotate=90,
  braid/.cd,
  strand 1/.style={red},
  height=1cm,
  width=1cm,
] (braid) at (1,2) {braid={s_1 s_2}};
\end{tikzpicture}

\end{document}

Output snippet:

Hmm, thought I'd fixed this one - but maybe it was a similar bug in one of my other packages.

Is this with the latest CTAN release or with the latest from this repository?

Possibly fixed in https://github.com/loopspace/braids/commit/57797339ad6ccc1bec0b20f97f450a1fd06a484f, or maybe another incantation of the same issue.

Oh, yeah this is whatever version is in texlive 2022; I should have tested with your latest update. I'll report back here when I do that, and probably close this issue.

[nilesjohnson]

confirmed; the warnings do not appear when I use the newer version here!
