Himyarite coin with ancient South Arabian script

Unicode has included letters for the ancient South Arabian script used in Himyarite coins for a long time but I have never seen them used except in sites about Unicode itself.

Here is a coin from mint 𐩧𐩺𐩵𐩬 (=RYDN, Raidan/Raydan, at Zafar in Yemen).

I am not sure what is needed to use South Arabian script on your computer. I have a nice font of them on Mac OS 10.12 rendered under Safari but not under Chrome or Firefox.

The mint name, Raydan, is encoded as follows:

𐩧 = R
𐩺 = Y
𐩵 = D
𐩬 = N

I had more difficultly with the name of the ruler. It is 𐩲]𐩵𐩬𐩽𐩨𐩺𐩬 (= ʿMDN BYN, Amdan Bayyin Yanuf). Two of the letters on the coin did not make sense.

𐩲 ?= is this ʿ (Ayn, the rough breathing mark)?
] ?= I couldn't find this one in the table
𐩵 = D
𐩬 = N
𐩽 ?= This looks like their digit 1, but I couldn't find any reason it appears here.
𐩨 = B
𐩺 = Y
𐩬 = N

I don't actually have Stuart Munro-Hay's book Coinage of Arabia Felix so I have been using his article “The coinage of Shabwa (Hadhramawt), and othe ancient south arabian coinage in the national museum, Aden” which is available online and includes information on inscriptions.

I would be curious to know which computer/browser combinations can see the ancient South Arabian characters above. I would also be curious if anyone knows the correct Unicode way to encode the letters I am uncertain of.
