About 0xA4 in ISIRI-3342, the current one is only my opponion. I think
it's really a currency sign that in a Persian-capable program/font, should
be rendered with a glyph variant shaped like the one you told.

It really depends. You may prefer to map it to the letters that make
"rial". But it will have problems with roundtrip.

(BTW, if you coded it to REH, FARSI YEH, ALEF, LAM, don't forget to add
ZERO WIDTH NON-JOINER before and after the sign if necessary.)

(BTW 2, there is also a standard Iranian keyboard, by ISIRI. Do you think
it will help if I provide a table soon?)
