From usability point of view such check will, in many cases, generate
annoyance, and bring nothing.
If I do not want to enter anything, and you "error me" to enter
"something", I'll do like this -
asdlöfjasdpoöfja spdfj as fsdaölkjf
And your check is dead. If you want "something", you will get "something".
It is hard (from usability point of view) to "validate" textarea to that
extent, and especially - to get reasonable answers...
I work for a scientific database, where all content providers are very
intelligent, well educated and very disciplined, and the content editors
still have hard time thinking how to guide the content provider so that
they provide reasonable input.
Your problem is not so much php related, but a usability and editorial one.
