Watch out for multibyte collations there. In the past, MW has had numerous issues with multibyte collations causing index lengths to almost double up and hit the limit.
VARBINARY doesn't have collations. Which is part of why we use it for everything. (Well, that and because Wikipedia runs on 4.0, which doesn't have collations for anything. :) ) A utf8 collation will triple the maximum size of the index, yes.
