 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.
