What bugs?

I asked for an example, you haven't provided, yet you blame others
without even considering that you might be doing or expecting
something wrong. So I'm asking again. Please show us an example along
the lines of: "I'm using the FooBar software, version 1.2.3, this and
that particular field. I enter a data, the hexdump of that data is
included here. I expect it to render as 123, instead it renders as
321."

I don't find it a nice attitude to blame others without having a
thorough understanding of the situation, without having firm reasons
to suspect the problem elsewhere rather than in your expectations.

And if a renderer is incorrect (which is not impossible, but maybe a
bit early to claim), you just have to ditch it and replace with a
correct one. Or, well, maybe your goal is to locate a set of faulty
renderers, locate and understand their exact bugs, and find a
workaround, i.e. a Unicode representation of numbers in RTL context
with narrow spaces which is immune to those bugs? Not sure if any of
us here are eager to help with that, I'm not, sorry. Not sure if it's
possible at all (if there are really such bugs), probably not, given
your further constraints such as not using BiDi control chars.
