I have recently noticed that when uploading .dwg files to one of our accounts, a number of fonts seem to have been corrupted when viewing the drawings via the Forge Viewer API (see screenshot below). This appears to have become a problem at some point in early August as up until this point, the same drawing would convert and display correctly.

We have seen this behaviour on several .dwg files uploaded in the last couple of weeks both in this account and another that we operate. No change has been made to the code in our application. Does anybody know what is causing this issue and advise on the best course of action for resolving these problems? I believe the fonts used are Swiss and Swiss Bold.
