I have a font oddity to report: if I use \setupalign [hanging,hz], the
lower case letter "a" disappears in a particular font.
This doesn't happen with other fonts and the missing letter comes back
if I remove \setupalign [hanging,hz].
If this is a bug that you would like to investigate, I would be happy
to send the font privately.

I think that my Octavian font cannot use hanging and the lower case letter “a” at the same time. This is very odd.

Hi Michael,
Your file works here without problems with the same ConTeXt and
LuaTeX, Version beta-0.47.0-2009121623.

Hi,
This was a bug in luatex: the function that copies the font
information from the base font to the expanded font did not
copy the last glyph at all. There is a one-character patch to
trunk/source/texk/web2c/luatexdir/font/texfont.c:
@@ -1094,7 +1094,7 @@
memcpy(math_param_base(k), math_param_base(f), i);
}
- for (i = 0; i < font_tables[f]->charinfo_count; i++) {
+ for (i = 0; i <= font_tables[f]->charinfo_count; i++) {
ci = copy_charinfo(&font_tables[f]->charinfo[i]);
font_tables[k]->charinfo[i] = *ci;
}
And that fixes it.
The only oddness with this particular font is that the 'a' happens
to be its last glyph in the ordering of the glyph implementations
inside the otf file. Usually, the last of those is something odd
like an alternate or a designer' logo, which is probably why nobody
noticed before.

That's weird, did you use Michaels font?
Best wishes,
