Just butting in here, if I recall correctly, both the PHP-native mb_strlen() and the MediaWiki fallback mb_strlen() functions are considerably slower (1.5 to 5 times as slow).
They only have to be run once, when the revision is saved. It's not likely to be a noticeable cost.
Yup, though we might as well remember that not everyone has mb_ functions installed. MediaWiki is intended to be functional both with, and without mb_ functions. That's another point towards storing both and falling back to bytes when the char field isn't populated.
