On a PC, Arial is the replacement for Helvetica and there is no native Helvetica on Windows. The Helvetica you installed may not be the same as the Helvetica on the MAC system (just the name being the same does not meant they are the same). What you want to do is probably best done with a form anyway, and just leave the form text to be the default font -- don't force it.
So, what is the problem with Arial? It is basically an equivalent font. If you want to edit the file on a PC, probably best to just let it revert to Arial and forget it.
The issue is this is a corporate thing, the CxO's want Helvetica, not Arial, and because the graphic designer and assistant work on Mac's they can create the stuff in Helvetica, however this is something that we want anybody to be able to modify after the fact. I would agree to simply let it use Arial except for the fact that the difference in the fonts is very obvious when sitting side by side. They would have to convert all their documents to Arial and probably redesign the whole thing when the spacing ends up different.
The font is technically the exact same font that was used on the Mac but I'm sure I know the reason it's not working in this case. The one question I can't seem to find the answer to in all my googling is how to get/purchase Helvetica for Windows. Not a similar font but the exact same version that's used on Macs.
Of course none of this addresses my issue of why it auto-reverts only when you select the converted Helvetica font. It seems like an unaddressed issue in the program where since nobody would probably run into this for the most part, they don't have anything implemented to catch the error and display a message telling you that you can't do that. Instead it just reverts it without any indiciation as to why it's reverting it.
Oh how I despise typography...
The relationship between Helvetica and Arial in PDF is more complicated than you might imagine.
Helvetica and Arial are considered absolutely interchangeable.
Helvetica has a special significance, it never needs to be embedded; all PDF viewers must display it.
Early releases of Acrobat included a copy of Helvetica and used it.
Later released of Acrobat switched to including a copy of Arial (they don't use the system Arial for that) which substitutes for Helvetica.
But if it is embedded, Acrobat might or might not show it, or might show a system Helvetica (if available), or Arial, according to settings.
I seem to remember comparing them and not seeing any differences. What letters do you see different?
The number 1 was very apparent which the flier happens to use a lot of. R's and A's are also noticeable with a curl on the bottom right. Of course you also have to realize these are fliers so the font size is proabably 72+ where it's going to be far more apparent.
Because of this we actually started looking at the fonts on a lot of their marketing pieces and realized they switch between Arial and Helvetica a lot between different fliers/brochures and whatnot.
I did find the right font pack that we need from Linotype.com but I don't want to purchase it only to find out Acrobat reverts to Arial just like it currently does because of the "interchangeability." I'm not quite sure what to do in this case as I'm sure they probably don't do refunds for font purchases. I think I'll have to take the question to Linotype though and report back if I still have issues with the "official" font auto-reverting.
Thanks for the help.
It odd Helvetica started out as an Aodobe Font and the original Fonts used on the first Mac were licensed from Adobe. Helvetica was so Popular Microsoft came out with Arial as an equivalent.
However there were differences so Apple came out with a licensed a version of Arial and MS licensed a version of Helvtica. So Both platforms have, or are supposed to have Both Arial and Helvetica on their systems.
What adobe chooses to do is up to Adobe. If the same font is on Both systems Acrobat or indesign or whatever is supposed to honor it. Whether they do or not who knows. I've sent PDF to people on PCs using. And they have had no issues. Even to the point of having to do touchups and same from me touching up stuff from PC's.
