I'm cleaning our my mailbox and I seem to forgot to forward this to
the list for archival. I'm doing so in hopes of addressing the issues
noted within.

As Owen observes, PuTTY doesn't include any fonts at all; those must
be the fonts already installed on your system. (I don't even _have_
Simplified Arabic Fixed.)

PuTTY currently displays diacritics by simply overlaying the
diacritic glyph on the primary glyph.
This is not ideal; in cases where a precomposed version of the
character exists, it probably ought to be used in place of this
overlaying trick, on the grounds that it's more likely to place the
diacritic in a legible position!
For unshaped scripts, I think the simplest specification would be to
normalise every character cell's contents into Unicode Normalisation
Form C or KC (I haven't worked out which yet), either on output
(just for display) or possibly even on input (so that cut and paste
returned normalised text as well).
For Arabic, I don't think it's that simple. The shaping code would
have to do the job: it would need to be told about diacritics on the
characters it was working with (which it will need anyway to handle
lam-alef correctly), and would have to pick different presentation
forms where they were available.

I know about that - all my own testing has been done using the
ae_fonts_mono X font from that page! :-)
