My first guess would be \nfss at catcodes which reset a lot of catcodes
before reading the font name: 

\def\DeclareFontShape{\begingroup
   \nfss at catcodes
   \expandafter\endgroup
   \DeclareFontShape@}

It is defined as 

\def\nfss at catcodes{%
     \makeatletter
     \catcode`\ 9%
     \catcode`\^^I9%
     \catcode`\^^M9%
     \catcode`\\\z@
     \catcode`\{\@ne
     \catcode`\}\tw@
     \catcode`\#6%
     \catcode`\^7%
     \catcode`\%14%
   \@makeother\<%
   \@makeother\>%
   \@makeother\*%
   \@makeother\.%
   \@makeother\-%
   \@makeother\/%
   \@makeother\[%
   \@makeother\]%
   \@makeother\`%
   \@makeother\'%
   \@makeother\"%
}

But as I have neither an utf8-font, nor the newest luatex currently
I can't try.
