I'm still not convinced. Sure you can ensure the field is de-facto PK,

as developer, should modify your model accordingly and keep it.

I tried to define maximal allowed characters count:
EXECUTE BLOCK (Description VARCHAR(10921) CHARACTER SET UNICODE_FSS

Ive thought about this - this is strange behavior.
It's because unicode doesn't store all chars in 2 or 3 or more bytes.
Only national chars are stored on more bytes. Standard US-ASCII (and
some others) are store on 1 byte to keep backward compatibility.
I wrote the same. And, if you look at text, ~99% of character there are
digits, english
I haven't read the whole thread, but shouldn't be better to use blob for
