Symbols from packages bbding and utfsym make package wrapfig2 not working properly

Question

I have the following code, trying to wrap an image with some sentences beginning with a symbol from packages bbding and utfsym. Probably the problem can occur using and other symbols packages. If I use any symbol from bbding package or a symbol from utfsym package with \large, \Large etc commands then the package wrapfig2 cannot "cut" the lines of text, and they overcame the image. Why this happens and how can we solve it? Here is the MWE:

\documentclass[12pt]{article}
\usepackage[a4paper, total={180mm,257mm},left=15mm,top=20mm]{geometry}
\usepackage{utfsym,bbding,wrapfig2}

\begin{document}
    
    \begin{wrapfigure}[7]{r}{0.4\textwidth}
        \begin{center}
            \setlength{\fboxsep}{0pt}%
            \setlength{\fboxrule}{2pt}%
            \vspace{-6mm}
            \fbox{\includegraphics[width=0.33\textwidth]{example-image}}
        \end{center}
        \caption{\footnotesize Example image}
    \end{wrapfigure}

    \usym{1F4D6} This is a test sentence \dotfill
    
    \usym{1F4D7} This is a test sentence \dotfill
    
    \usym{1F4E1} This is a test sentence \dotfill
    
    {\large \usym{1F4D6}} This is a test sentence \dotfill
    
    \PencilRightDown \dotfill
    
    \dotfill
\end{document}

Answer 1

wrapfig has to change the shape of paragraphs at the begin of a paragraph. This code fails if the begin is inside a group. (The bbding commands open a group without leaving vmode first). Use \leavevmode to start the paragraph:

\documentclass[12pt]{article}
\usepackage[a4paper, total={180mm,257mm},left=15mm,top=20mm]{geometry}
\usepackage{utfsym,bbding,wrapfig2}

\begin{document}
    
    \begin{wrapfigure}[7]{r}{0.4\textwidth}
        \begin{center}
            \setlength{\fboxsep}{0pt}%
            \setlength{\fboxrule}{2pt}%
            \vspace{-6mm}
            \fbox{\includegraphics[width=0.33\textwidth]{example-image}}
        \end{center}
        \caption{\footnotesize Example image}
    \end{wrapfigure}

    \usym{1F4D6} This is a test sentence \dotfill
    
    \usym{1F4D7} This is a test sentence \dotfill
    
    \usym{1F4E1} This is a test sentence \dotfill \par
    
    \leavevmode{\large \usym{1F4D6}} This is a test sentence \dotfill
    
    \leavevmode\PencilRightDown \dotfill
    
    \dotfill
\end{document}
