I just upgraded to 11.5 for Mac. When I opened an existing file I developed in 10.1, the embedded fonts went bizarre. I had Times embedded and it did some strange substitutions like the "i"s are in a totally different font as are the question marks. The whole font sets were embedded. No subsetting. Can someone enlighten me as to what is going on?
One of the new features in Director 11.x is a new text engine that does Unicode. Whether it is an improvement or not is up in the air. Anyway, it has new problems. It is quite common to have embedded font problems with projects updated from Director 10. Generally, you can fix them by deleting the embedded font and re-embedding it in Director 11. Just keep the same menber name and it should be fine.
