Could you please also update the regular expression in PEP 263 to
"^[ \t\v]*#.*?coding[:=][ \t]*([-.a-zA-Z0-9]+)"?
Coding cookie must be in comment, only the first occurrence in the line
must be taken to account (here is a bug in CPython), encoding name must
be ASCII, and there must not be any Python statement on the line that
contains the encoding declaration.
