I`m able to sanitize characters, but complex sequences will be problem. I
will look on this, but I don`t know, if I`m able to do this.

My main interest on this was in rst. I`m using markdown only in github
issues and my knowldge about md is poor.

Yes, it looks it is done by linestyle.

jelen=# SELECT 1;

| ?column? |
|----------|
| 1 |

(1 row)

jelen=# \pset linestyle unicode
Line style is unicode.
jelen=# SELECT 1;

│ ?column? │
|----------|
│ 1 │

(1 row)

jelen=#

I have prepared linestyle for rst and md, but I can`t switch linestyle
outside, because if i did it
\pset linestyle
wrote "markdown" or "rst".
I see, problem is only in cells borders, I will correct this.
