Warnings concerning "Missing character: There is no * in font nullfont!" when naming an object

[Holiverse]

Is there an existing issue for this?

• [X] I have searched the existing issues

Current behaviour

When using the lateste version of Co-Di. Similar to the #42 , if we name objects, there are also some extra warnings.

For example

\documentclass[10pt]{article}

\usepackage{commutative-diagrams} 

\begin{document}

\title{Test}
\maketitle

\begin{codi}
    \obj{
                |(C)|C & |(Z)|Z(M)\\
                & |(M)|M\\
            };
    \mor[swap]: C F:-> M;
    \mor: * "F'":-> Z "Forg":-> *; 
\end{codi}

\end{document}

I believe this issue is similar to #42 and the number of warnings is much less than before.

Thanks for spotting this @Holiverse!

I fixed three sources of pollution for the logs:

• 689e6377656266b379fe8f3b57ce693caa43ed31 fixes Missing character: There is no * in font nullfont! for characters in the node names of \obj (this is the one you are pointing to above);
• c5af72407237b146299e5ee8c24e8ec37cb0f5b6 fixes Missing character: There is no ; in font nullfont! produced by \mor;
• 6729ffd5447ea9b5e114ce786ec9102f9093bd7f fixes Streaks of "ABYN" generated by \mor when using the matrix syntax.

Logs should be clean now.

These fixes are included in v1.1.2, just released, available here and soon on CTAN.
