I created a PDF (export from InDesign CS) and opened it in Acrobat
6.01. All PDFs exported from ID have "embedded subset" turned on by
default.

Everything looked fine in Acro, Document Info/Fonts listed about 8
fonts all "Embedded Subset" with character encoding of "Identity-H".

Question 1: What does "Identity-H" mean?

I found one typo (2 words missing a space between them) in the doc.

So I used the Text Touchup tool to add the space. When I clicked with
it in the sentence, I saw the progress bar in the status area slowly
load up, something about "reading system fonts." I assume it's
checking to see if I have the font I'm about to edit installed on my
Mac. I have the font loaded so it appeared to be no biggie ... I just
added the space.

Question 2: If I didn't have the font loaded, I assume Acro would
still let me edit the text but it would create an "approximation" of
the font via its Adobe MM's. Correct? Does it make a difference what
type of edits I do to a font I don't have available... e.g., what if
I just want to delete a character (I don't need access to the font
for that), or add a character already embedded elsewhere, vs. adding
a new glyph or size that doesn't exist elsewhere?

Question 3: If Acro has to use a fake font to make my edit, is it
just my edit that get the fake font, or all the characters in the
whole doc that are that font?

Anyway... after making the edit and saving, I went back to Document
Info/Fonts. There was a change. For the font that I added the space
(Myriad Roman), instead of saying "Encoding: Identity-H" like before,
and like the rest of them, it now said "Encoding: Custom"

Question 4: Is that something I have to be worried about... as far as
recipients on any platform being able to see this doc using Myriad
Roman as originally set?

Thanks
