\verb+\#+ instead of \verb+\HChar{35}+ is problematic
when sent to aux file as \verb+#+.

We had also \verb'\append:def\@begindocumenthook{\HLet\"|=\ddot}' in
babel. It gets russian and brazil into infinite loop.  Why it was
inserted.

\`'\def\x:unicode#1{\HCode{&}\HChar{-35}\HCode{x#1;}}' is not a slution
because the mathml marking on it get confused.

We use \`'\protect' with LaTeX, because compilation can fail in temporary files,
especially in TOC like environments.
