We publish our files ps and distill them to get the file down to a manageable file size. We have found that if you select some text in the pdf you get ) instead of words. If I go to edit pdf in Acrobat it tells me that the font is calibri so It seems to find the font. Where do I look for the issue.
I suspect this has to do with font subset embedding. If you embed only a subset of the font, it only includes the glyphs that are used in the document, and I think in that case it uses a custom encoding to index the reduced set of characters.
I would try tweaking your distiller settings to embed full fonts instead of subsets and see if that helps.
