[development] Form field maxlengths vs. database field sizes

[Karthik]

This issue stems from Killes' comment [
http://drupal.org/node/46306#comment-71971 ]. Should form field
maxlengths be consistent with corresponding database field sizes or
should unicode encoding be accounted for?

This is especially in light of the fact that 4.7 now converts all
existing databases to UTF-8, but also retains support for (MySQL)
3.23.58.

Or should we just not use maxlengths at all?

Thanks
