Yes. :-) The definition of \newunicodechar is essentially (only
some consistency checks are omitted here)

\def\newunicodechar#1#2{%
  \catcode`#1=\active
  \begingroup\lccode`\~=`#1
  \lowercase{\endgroup\protected\def~}{#2}}

What's in #2 has already been tokenized when the catcode of #1
is changed. Actually the catcode change might even be deferred
at a later moment. Of course I don't expect that anybody calls
\newunicodechar inside a group.

Ciao
