Length() is perfectly consistant with the value's type. As you've
demonstrated, Sqlite does not respect the column types in tables
as declared in the CREATE statement.
Length(text_value) always returns the number of characters and
length(blob_value) always returns the number of bytes. The type

I remember a few months ago noticing it would count UTF-8 chars, not
bytes, so it would not
The built-in Sqlite length() function works just fine on blobs:

5
Why do you think it doesn't?

I'd like to be corrected if I am wrong, but I

Great!

And no, length() doesn't work on Blob.
