Note: I removed \autoref{alice}. It wasn't necessary. New file is:

\caption{5\% \label{_fred}}
envolope

Debugger gives:
ispell-region: string pos (29->37), eol: 37, [in-comment]: [nil],
[add-comment]: [nil], [string]: [^envolope

Running:
/usr/bin/aspell -a -m -d en --encoding=utf-8

Inputting:
^envolope

Output:
& envolope 7 1: envelope, enveloper, envelop, enveloped, envelopes,
envelops, envelope's

This output looks sensible, but the spelling options do not appear in the
emacs buffer.
