Obelus and Metobelus characters?

Hello!

I'm trying to find out if there are "somwhere in Unicode" the
characters used in ancient greek textual criticism, the so-called
"obelus" and "metobelus signs". See this:

I found following signs, none of them seems to be exactly
what I'm looking for:

 U+070B SYRIAC HARKLEAN OBELUS
 U+070C SYRIAC HARKLEAN METOBELUS

The obelus seems like to be the right shape, but it is a RTL
character. I further found these suggested to have the
function of obelus, but they have quite different shapes:

 U+2020 DAGGER
 U+00F7 DIVISION SIGN

My question is thus: have I missed something?

Thank You!

P.T.
