Guys, I discovered a problem: I have plenty of pdf's that I store on dropbox. On my ipad, I open them on Goodreader, and mark them up, then sync them back to dropbox. When I then try to copy and paste something from those pdf's I only get symbols (but not BEFORE I read them on ipad, only after the sync). This applies to pdfs/docs with fonts not stored on the ipad, I think - it gets displayed perfectly, but through the ipad iteration loses the copy/paste readability for a word processor. I cannot install a font on the ipad, and I cannot change the font in the pdfs not produced by myself (can I)? What's the loophole for that? does the pdf file also lose searchability through this?
