I have the following written in my permeable for my dedication page:
\newcommand{\dedicationpage}{
\newpage \thispagestyle{plain}
\font\chan=pzcmi at 12pt
\vspace*{\fill}
\begin{center}
\scshape
\chan \input{frontmatter/dedication}
\vspace*{\fill} \newpage \rm
\end{center}
}
And my dedication page has the following:
{\textbf{Dedicated \protect\\ to}}
\newline
\vspace{10mm}
{this is the first line \protect\\ and this is the second line}
And it turns out only "this is the first line and this is the second line" works in the designed font, but not the ”Dedicated to“ part. Could you help point out what the problem is here? Thanks!

\fontshould be banished from using LaTeX.;-)– egreg Dec 18 '16 at 17:22\textbf{}isn't like the little B button in Microsoft Word and does not, by default, fake bold. What it does is use the typeface that is specified as bold, so you have to use a font which has a bold version, or you must declare some other bold face for use by\textbf{}. – Au101 Dec 18 '16 at 17:32
