My sources (including ISIRI 6219 and ISIRI 9147) are explicitly mentioning that use of Solidus in place of "ممیز" (decimal separator) is not correct. Using Solidus is implying division and fraction. This character is placed on Shift+E02 while Solidus is on

This is 3.14:


This is 3⁄14 (=3÷14):


The source of this confusion is because U+066B should be rendered as glyph vaguely half the size of Solidus and with smaller or equal right angle.

What Shervin said. Basically slash is not the character to use. It also creates some bidi issues we need to avoid.

The original report is probably due to a font not optimized for Persian. The range of acceptable Persian glyphs for the decimal separator is smaller than that of Arabic. See Noto Naskh Arabic for a good shape.

Thanks for the feedback! I will wait until the committee has a look, but we can probably resolve this as invalid or as-designed.

Seems like the issue is really about correct display in the font, not about the character used.
