It should be added (after investigation of similarity) to font-helpers.

I discovered that U+A789 is not equal to ":" and U+A78A != "=", see e.g. 
Gentium font. U+A78D Ɥ in unicode pdf table is displayed as "H" without a 
half of left stem, so it hardly the same as U+0427. Everething else is copied 
now using font-helpers scripts or directly (U+019F).

For U+A789 and U+A78A, it's probably better if they are not copies of colon and 
equal, they should probably be narrower or shorter so they are distinguishable.

For U+A78D see http://www.dkuug.dk/jtc1/SC2/WG2/docs/n3481.pdf
There are several forms to uppercase letter turned h: one is an H without the 
bottom half left stem (page 4 figure 1, like in Unicode 6.0 charts), one is an 
large turned h (page 5 figure 2), and one is like Ч U+0427 (page 3).
The form is really font dependent, and the Unicode charts are not prescriptive 
so it's up to the font designer to choose what form is better.

Either form is correct, copying U+0427 is just easier.
