Missing Mark Glyph TAH BELOW

[graphicore]

I'm currently in the process of decomposing glyphs into base form + marks.

Unfortunately some marks are missing.

For example:

before we did to create the final form of uni076E:

sub uni076E by uni076E.fina;

however, because we don't want to create so many different ligatures, it's important that we can decompose this, e.g.:

subuni076E by uniFEA2 uniFBC1;

Where:

076E: ARABIC LETTER HAH WITH SMALL ARABIC LETTER TAH BELOW FEA2: ARABIC LETTER HAH FINAL FORM FBC1: ARABIC SYMBOL SMALL TAH BELOW

However uniFBC1 is missing uni076E.fina is instead constructed with uni0615

I think I don't need a unicode encoded tah below (uniFBC1), a letter tah.below would be sufficient. This is up to you.The problem with the uni0615 mark is that it goes to the anchor above. I need a version that goes to the anchor below.

Issue has been fixed, just added uniFBC1 (tahbelow-ar) and replaced it with uni0615 (tahabove-ar) in intended Character both in Mirza and Katibeh
