I looked at documentation and I decided to add command \textminussuperior


I knew that it is actually definition of \texttwosuperior but I
decided to play with {\80\262} later. However it lead me to

! TeX capacity exceeded, sorry [input stack size=5000].
\textminussuperior ->\PU-cmd \textminussuperior
l.4298 ...ussuperior\ } in the remainder estimate}
!  ==> Fatal error occurred, the output PDF file is not finished!

Is the reason that I placed a declaration into preamble instead of
some external file?
I tried to place it both before/after \usepackage[]{hyperref} with the
same results

How one can declare other powers?
