Sorry my mistake. It must have been another font then that does this
'back-up' operation. Nonetheless, if the intention is to provide a
legible text (which is not the case with last resort) the specific
problem with Arabic script regarding this kind of operations remains.
I guess I now know what font is being discussed here. It never shows
up in practical use for Arabic script. Only when I dig into Arabic
Presentation Forms A and B, which are never encoded in Arabic script
anyway (and shouldn't be). SIL fonts that I mentioned by the way,
don't cover those presentation forms either.
Yes I think Last Resort is a quick way to realize what is missing.
And it doesn't require expertise by the user. The rest is up to the
user. I just didn't know that those square signs that I occasionally
see were actually coming from Last Resort!
