PDF export/print creates kerning/tracking shifts in print.
About 2 weeks ago, the PDF printing and exporting started to exhibit a strange behavior. The space between characters is completely different than the font displays when editing, or on any other print medium. Even the simple word "the": 't' and 'h' are mashed together with too much space before the 'e'.
I know this is happening on Arial and Verdana at a minimum. I can reproduce it on a brand new document with just one line of text. Only PDF seems to be effects, and Word exports look ok.
Another observation: This problem started about two weeks ago when the PDFs being created stopped having spaces in their names and now have the + character instead.
