First, there are many real problems that need to be fixed in the

Second, authors should not be encouraged to use such rarely used and never

I wonder why you don't mention the most obvious alternative.

I didn't see any reference to them in the question, and I think very few
people actually use them, and hardly anyone _needs_ them.

Depending on what you imagine as the potential use of box drawing

I would suggest upgrading from XHTML 1.0 to HTML 4.01. Actually the page
is not even XHTML 1.0, though a validator won't notice this. The XHTML 1.0
