You're close.  Try

$line[7] =~ s/\[font.*?]//g

Note the use of the non-greedy match (the *?, instead of just *).  If
you don't do this, it will match everything from the first font tag in
the line up to the last ] in the line, whether or not it's part of the
font tag.

The other, typical alternative is

s/\[font[^\]]*]//g

the [\]] matches any character that is *not* a ], so the regex won't
end up matching beyond the font tag.
